Four offset voltage grades are available (C-suffix and I-suffix types), ranging from the low-cost TLC272 (10 mV) to the high-precision TLC277 (500 µV). These advantages, in combination with good common-mode rejection and supply voltage rejection, make these devices a good choice for new state-of-the-art designs as well as for upgrading existing designs.

Add R suffix to the device type (e.g., TLC277CDR). description (continued) In general, many features associated with bipolar technology are available on LinCMOS operational amplifiers without the power penalties of bipolar technology. General applications such as transducer interfacing, analog calculations, amplifier blocks, active filters, and signal buffering are easily designed with the TLC272 and TLC277. The devices also exhibit low voltage single-supply operation, making them ideally suited for remote and inaccessible battery-powered applications. The common-mode input voltage range includes the negative rail. A wide range of packaging options is available, including small-outline and chip carrier versions for high-density system applications. The device inputs and outputs are designed to withstand –100-mA surge currents without sustaining latch-up. The TLC272 and TLC277 incorporate internal ESD-protection circuits that prevent functional failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.2; however, care should be exercised in handling these devices as exposure to ESD may result in the degradation of the device parametric performance. The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized for operation from – 40°C to 85°C. The M-suffix devices are characterized for operation over the full military temperature range of – 55°C to 125°C. 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 TLC272, TLC272A, TLC272B, TLC272Y, TLC277 LinCMOS PRECISION DUAL OPERATIONAL AMPLIFIERS SLOS091B – OCTOBER 1987 – REVISED AUGUST 1994 equivalent schematic (each amplifier) VDD P3 P4 R6 R1 N5 R2 IN – P5 P1 P6 P2 IN + R5 C1 OUT N3 N1 R3 N2 D1 N4 R4 N6 N7 R7 D2 GND TLC272Y chip information This chip, when properly assembled, displays characteristics similar to the TLC272C.

split-supply test circuits Because the TLC272 and TLC277 are optimized for single-supply operation, circuit configurations used for the various tests often present some inconvenience since the input signal, in many cases, must be offset from ground. This inconvenience can be avoided by testing the device with split supplies and the output load tied to the negative rail. A comparison of single-supply versus split-supply test circuits is shown below. The use of either circuit gives the same result.

The bias current at normal room ambient temperature is typically less than 1 pA, a value that is easily exceeded by leakages on the test socket. Two suggestions are offered to avoid erroneous measurements: 1. Isolate the device from other potential leakage sources. Use a grounded shield around and between the device inputs (see Figure 4). Leakages that would otherwise flow to the inputs are shunted away. 2. Compensate for the leakage of the test socket by actually performing an input bias current test (using a picoammeter) with no device in the test socket. The actual input bias current can then be calculated by subtracting the open-socket leakage readings from the readings obtained with a device in the test socket. One word of caution: many automatic testers as well as some bench-top operational amplifier testers use the servo-loop technique with a resistor in series with the device input to measure the input bias current (the voltage drop across the series resistor is measured and the bias current is calculated). This method requires that a device be inserted into the test socket to obtain a correct reading; therefore, an open-socket reading is not feasible using this method. 8 5 V = VIC 1 4 Figure 4. Isolation Metal Around Device Inputs (JG and P packages) low-level output voltage To obtain low-supply-voltage operation, some compromise was necessary in the input stage. This compromise results in the device low-level output being dependent on both the common-mode input voltage level as well as the differential input voltage level. When attempting to correlate low-level output readings with those quoted in the electrical specifications, these two conditions should be observed. If conditions other than these are to be used, please refer to Figures 14 through 19 in the Typical Characteristics of this data sheet. input offset voltage temperature coefficient Erroneous readings often result from attempts to measure temperature coefficient of input offset voltage. This parameter is actually a calculation using input offset voltage measurements obtained at two different temperatures. When one (or both) of the temperatures is below freezing, moisture can collect on both the device and the test socket. This moisture results in leakage and contact resistance, which can cause erroneous input offset voltage readings. The isolation techniques previously mentioned have no effect on the leakage since the moisture also covers the isolation metal itself, thereby rendering it useless. It is suggested that these measurements be performed at temperatures above freezing to minimize error. POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 17 TLC272, TLC272A, TLC272B, TLC272Y, TLC277 LinCMOS PRECISION DUAL OPERATIONAL AMPLIFIERS SLOS091B – OCTOBER 1987 – REVISED AUGUST 1994 PARAMETER MEASUREMENT INFORMATION full-power response Full-power response, the frequency above which the operational amplifier slew rate limits the output voltage swing, is often specified two ways: full-linear response and full-peak response. The full-linear response is generally measured by monitoring the distortion level of the output while increasing the frequency of a sinusoidal input signal until the maximum frequency is found above which the output contains significant distortion. The full-peak response is defined as the maximum output frequency, without regard to distortion, above which full peak-to-peak output swing cannot be maintained. Because there is no industry-wide accepted value for significant distortion, the full-peak response is specified in this data sheet and is measured using the circuit of Figure 1. The initial setup involves the use of a sinusoidal input to determine the maximum peak-to-peak output of the device (the amplitude of the sinusoidal wave is increased until clipping occurs). The sinusoidal wave is then replaced with a square wave of the same amplitude. The frequency is then increased until the maximum peak-to-peak output can no longer be maintained (Figure 5). A square wave is used to allow a more accurate determination of the point at which the maximum peak-to-peak output is reached. (a) f = 1 kHz (b) BOM > f > 1 kHz (c) f = BOM (d) f > BOM Figure 5. Full-Power-Response Output Signal test time Inadequate test time is a frequent problem, especially when testing CMOS devices in a high-volume, short-test-time environment. Internal capacitances are inherently higher in CMOS than in bipolar and BiFET devices and require longer test times than their bipolar and BiFET counterparts. The problem becomes more pronounced with reduced supply levels and lower temperatures. 18 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 TLC272, TLC272A, TLC272B, TLC272Y, TLC277 LinCMOS PRECISION DUAL OPERATIONAL AMPLIFIERS SLOS091B – OCTOBER 1987 – REVISED AUGUST 1994 TYPICAL CHARACTERISTICS Table of Graphs FIGURE VIO αVIO Input offset voltage Distribution 6, 7 Temperature coefficient of input offset voltage Distribution 8, 9 VOH High-level g output voltage g vs High-level High level output out ut current vs Supply y voltage g vs Free-air temperature 10, 11 12 13 VOL Low level output voltage Low-level vs Common-mode Common mode input in ut voltage vs Differential input voltage g vs Free-air temperature vs Low-level output current 14, 15 16 17 18, 19 AVD Large-signal g g differential voltage g amplification vs Su Supply ly voltage vs Free-air temperature vs Frequency 20 21 32, 33 IIB IIO Input bias current vs Free-air temperature 22 Input offset current vs Free-air temperature 22 VIC Common-mode input voltage vs Supply voltage 23 IDD Supply current vs Supply y voltage g vs Free-air temperature 24 25 SR Slew rate vs Supply y voltage g vs Free-air temperature 26 27 Normalized slew rate vs Free-air temperature 28 Maximum peak-to-peak output voltage vs Frequency 29 B1 Unity gain bandwidth Unity-gain vs Free-air temperature vs Supply voltage 30 31 φm Phase margin g vs Su Supply ly voltage vs Free-air temperature vs Load capacitance 34 35 36 Vn Equivalent input noise voltage vs Frequency 37 Phase shift vs Frequency 32, 33 VO(PP) POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 19 TLC272, TLC272A, TLC272B, TLC272Y, TLC277 LinCMOS PRECISION DUAL OPERATIONAL AMPLIFIERS SLOS091B – OCTOBER 1987 – REVISED AUGUST 1994 TYPICAL CHARACTERISTICS DISTRIBUTION OF TLC272 INPUT OFFSET VOLTAGE DISTRIBUTION OF TLC272 INPUT OFFSET VOLTAGE Percentage of Units – % 50 40 ÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌ ÌÌÌÌÌ ÌÌÌÌÌ 60 753 Amplifiers Tested From 6 Wafer Lots VDD = 5 V TA = 25°C P Package 50 Percentage of Units – % 60 30 20 40 ÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌ ÌÌÌÌ 753 Amplifiers Tested From 6 Wafer Lots VDD = 10 V TA = 25°C P Package 30 20 10 10 0 –5 0 –4 –3 –2 –1 0 1 2 3 VIO – Input Offset Voltage – mV 4 –5 5 –4 DISTRIBUTION OF TLC272 AND TLC277 INPUT OFFSET VOLTAGE TEMPERATURE COEFFICIENT 40 DISTRIBUTION OF TLC272 AND TLC277 INPUT OFFSET VOLTAGE TEMPERATURE COEFFICIENT ÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌ 60 324 Amplifiers Tested From 8 Wafer Lots VDD = 5 V TA = 25°C to 125°C P Package Outliers: (1) 20.5 µV/°C 50 Percentage of Units – % Percentage of Units – % 50 30 20 40 324 Amplifiers Tested From 8 Wafer Lots VDD = 5 V TA = 25°C to 125°C P Package Outliers: (1) 21.2 µV/°C 30 20 10 10 0 0 2 – 10 – 8 – 6 – 4 – 2 4 6 8 αVIO – Temperature Coefficient – µV/°C 10 0 2 4 6 8 – 10 – 8 – 6 – 4 – 2 0 αVIO – Temperature Coefficient – µV/°C Figure 9 Figure 8 20 5 4 Figure 7 Figure 6 60 –3 –2 –1 0 1 2 3 VIO – Input Offset Voltage – mV POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 Á 10 TLC272, TLC272A, TLC272B, TLC272Y, TLC277 LinCMOS PRECISION DUAL OPERATIONAL AMPLIFIERS SLOS091B – OCTOBER 1987 – REVISED AUGUST 1994 TYPICAL CHARACTERISTICS† HIGH-LEVEL OUTPUT VOLTAGE vs HIGH-LEVEL OUTPUT CURRENT HIGH-LEVEL OUTPUT VOLTAGE vs HIGH-LEVEL OUTPUT CURRENT 16 VID = 100 mV TA = 25°C See Note A 4 VOH V OH – High-Level Output Voltage – V VOH VOH – High-Level Output Voltage – V 5 VDD = 5 V 3 VDD = 4 V VDD = 3 V 2 ÁÁ ÁÁ ÁÁ ÁÁ ÁÁ ÁÁ 1 0 –2 –4 –6 –8 IOH – High-Level Output Current – mA 0 – 10 14 VDD = 16 V VID = 100 mV TA = 25°C 12 10 8 VDD = 10 V 6 4 2 0 0 – 5 – 10 – 15 – 20 – 25 – 30 – 35 – 40 IOH – High-Level Output Current – mA NOTE A: The 3-V curve only applies to the C version.

This design includes an input common-mode voltage range that encompasses ground as well as an output voltage range that pulls down to ground. The supply voltage range extends down to 3 V (C-suffix types), thus allowing operation with supply levels commonly available for TTL and HCMOS; however, for maximum dynamic range, 16-V single-supply operation is recommended. Many single-supply applications require that a voltage be applied to one input to establish a reference level that is above ground. A resistive voltage divider is usually sufficient to establish this reference level (see Figure 38). The low input bias current of the TLC272 and TLC277 permits the use of very large resistive values to implement the voltage divider, thus minimizing power consumption. The TLC272 and TLC277 work well in conjunction with digital logic; however, when powering both linear devices and digital logic from the same power supply, the following precautions are recommended: 1. Power the linear devices from separate bypassed supply lines (see Figure 39); otherwise, the linear device supply rails can fluctuate due to voltage drops caused by high switching currents in the digital logic. 2. Use proper bypass techniques to reduce the probability of noise-induced errors. Single capacitive decoupling is often adequate; however, high-frequency applications may require RC decoupling.

Exceeding this specified range is a common problem, especially in single-supply operation. Note that the lower range limit includes the negative rail, while the upper range limit is specified at VDD – 1 V at TA = 25°C and at VDD – 1.5 V at all other temperatures. The use of the polysilicon-gate process and the careful input circuit design gives the TLC272 and TLC277 very good input offset voltage drift characteristics relative to conventional metal-gate processes. Offset voltage drift in CMOS devices is highly influenced by threshold voltage shifts caused by polarization of the phosphorus dopant implanted in the oxide. Placing the phosphorus dopant in a conductor (such as a polysilicon gate) alleviates the polarization problem, thus reducing threshold voltage shifts by more than an order of magnitude. The offset voltage drift with time has been calculated to be typically 0.1 µV/month, including the first month of operation. Because of the extremely high input impedance and resulting low bias current requirements, the TLC272 and TLC277 are well suited for low-level signal processing; however, leakage currents on printed-circuit boards and sockets can easily exceed bias current requirements and cause a degradation in device performance. It is good practice to include guard rings around inputs (similar to those of Figure 4 in the Parameter Measurement Information section). These guards should be driven from a low-impedance source at the same voltage level as the common-mode input (see Figure 40). Unused amplifiers should be connected as grounded unity-gain followers to avoid possible oscillation. noise performance The noise specifications in operational amplifier circuits are greatly dependent on the current in the first-stage differential amplifier. The low input bias current requirements of the TLC272 and TLC277 result in a very low noise current, which is insignificant in most applications. This feature makes the devices especially favorable over bipolar devices when using values of circuit impedance greater than 50 kΩ, since bipolar devices exhibit greater noise currents. – OUT + + (b) INVERTING AMPLIFIER OUT VI + – (a) NONINVERTING AMPLIFIER – VI VI OUT (c) UNITY-GAIN AMPLIFIER Figure 40. Guard-Ring Schemes output characteristics The output stage of the TLC272 and TLC277 is designed to sink and source relatively high amounts of current (see typical characteristics). If the output is subjected to a short-circuit condition, this high current capability can cause device damage under certain conditions. Output current capability increases with supply voltage. All operating characteristics of the TLC272 and TLC277 are measured using a 20-pF load. The devices can drive higher capacitive loads; however, as output load capacitance increases, the resulting response pole occurs at lower frequencies, thereby causing ringing, peaking, or even oscillation (see Figure 41). In many cases, adding a small amount of resistance in series with the load capacitance alleviates the problem. 30 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 TLC272, TLC272A, TLC272B, TLC272Y, TLC277 LinCMOS PRECISION DUAL OPERATIONAL AMPLIFIERS SLOS091B – OCTOBER 1987 – REVISED AUGUST 1994 APPLICATION INFORMATION output characteristics (continued) (b) CL = 130 pF, RL = NO LOAD (a) CL = 20 pF, RL = NO LOAD 2.5 V – VO + VI TA = 25°C f = 1 kHz VIPP = 1 V CL – 2.5 V (c) CL = 150 pF, RL = NO LOAD (d) TEST CIRCUIT Figure 41. Effect of Capacitive Loads and Test Circuit Although the TLC272 and TLC277 possess excellent high-level output voltage and current capability, methods for boosting this capability are available, if needed. The simplest method involves the use of a pullup resistor (RP) connected from the output to the positive supply rail (see Figure 42). There are two disadvantages to the use of this circuit. First, the NMOS pulldown transistor N4 (see equivalent schematic) must sink a comparatively large amount of current. In this circuit, N4 behaves like a linear resistor with an on resistance between approximately 60 Ω and 180 Ω, depending on how hard the operational amplifier input is driven. With very low values of RP, a voltage offset from 0 V at the output occurs. Second, pullup resistor RP acts as a drain load to N4 and the gain of the operational amplifier is reduced at output voltage levels where N5 is not supplying the output current.

Resistive Pullup to Increase VOH Figure 43. Compensation for Input Capacitance feedback Operational amplifier circuits almost always employ feedback, and since feedback is the first prerequisite for oscillation, some caution is appropriate. Most oscillation problems result from driving capacitive loads (discussed previously) and ignoring stray input capacitance. A small-value capacitor connected in parallel with the feedback resistor is an effective remedy (see Figure 43). The value of this capacitor is optimized empirically. electrostatic discharge protection The TLC272 and TLC277 incorporate an internal electrostatic discharge (ESD) protection circuit that prevents functional failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.2. Care should be exercised, however, when handling these devices as exposure to ESD may result in the degradation of the device parametric performance. The protection circuit also causes the input bias currents to be temperature dependent and have the characteristics of a reverse-biased diode. latch-up Because CMOS devices are susceptible to latch-up due to their inherent parasitic thyristors, the TLC272 and TLC277 inputs and outputs were designed to withstand –100-mA surge currents without sustaining latch-up; however, techniques should be used to reduce the chance of latch-up whenever possible. Internal protection diodes should not, by design, be forward biased. Applied input and output voltage should not exceed the supply voltage by more than 300 mV. Care should be exercised when using capacitive coupling on pulse generators. Supply transients should be shunted by the use of decoupling capacitors (0.1 µF typical) located across the supply rails as close to the device as possible. The current path established if latch-up occurs is usually between the positive supply rail and ground and can be triggered by surges on the supply lines and/or voltages on either the output or inputs that exceed the supply voltage. Once latch-up occurs, the current flow is limited only by the impedance of the power supply and the forward resistance of the parasitic thyristor and usually results in the destruction of the device. The chance of latch-up occurring increases with increasing temperature and supply voltages. 32 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 TLC272, TLC272A, TLC272B, TLC272Y, TLC277 LinCMOS PRECISION DUAL OPERATIONAL AMPLIFIERS SLOS091B – OCTOBER 1987 – REVISED AUGUST 1994 APPLICATION INFORMATION 10 kΩ 10 kΩ 0.016 µF 0.016 µF 10 kΩ – 10 kΩ 5V 10 kΩ 1/2 TLC272 – 1/2 TLC272 – VI 1/2 TLC272 Low Pass + + + High Pass 5 kΩ Band Pass R = 5 kΩ(3/d-1) (see Note A) NOTE A: d = damping factor, 1/Q Figure 44.

These devices use Texas instruments silicon-gate LinCMOS TM technology, which provides offset voltage stability far exceeding the stability available with conventional metal-gate processes. LinCMOS is a trademark of Texas Instruments Incorporated. The extremely high input impedance, low bias currents, and high slew rates make these costeffective devices ideal for applications which have previously been reserved for BiFET and NFET products. Four offset voltage grades are available (C-suffix and I-suffix types), ranging from the low-cost TLC272 (10 mV) to the high-precision TLC277 (500 uV). These advantages, in combination with good common-mode rejection and supply voltage rejection, make these devices a good choice for new state-of-the-art designs as well as for upgrading existing designs. The D package is available taped and reeled. Add R suffix to the device type (e.g., TLC277CDR). In general, many features associated with bipolar technology are available on LinCMOSTM operational amplifiers without the power penalties of bipolar technology. General applications such as transducer interfacing, analog calculations, amplifier blocks, active filters, and signal buffering are easily designed with the TLC272 and TLC277. The devices also exhibit low voltage single-supply operation, making them ideally suited for remote and inaccessible battery-powered applications. The common -mode input voltage range includes the negative rail. A wide range of packaging options is available, including small-outline and chip carrier versions for high-density system applications. The device inputs and outputs are designed to withstand -100-mA surge currents without 3 of 4 sustaining latch-up. The TLC272 and TLC277 incorporate internal ESD-protection circuits that prevent functional failures at voltages up to 2000 V as tested under MIL -STD-883C, Method 3015.2; however, care should be exercised in handling these devices as exposure to ESD may result in the degradation of the device parametric performance. The C-suffix devices are characterized for operation from 0°C to 70°C. The I -suffix devices are characterized for operation from -40°C to 85°C. The M-suffix devices are characterized for operation over the full military temperature range of -55°C to 125°C.

These advantages, in combination with good common-mode rejection and supply voltage rejection, make these devices a good choice for new state-of-the-art designs as well as for upgrading existing designs. The D package is available taped and reeled. Add R suffix to the device type (e.g., TLC277CDR). In general, many features associated with bipolar technology are available on LinCMOSTM operational amplifiers without the power penalties of bipolar technology. General applications such as transducer interfacing, analog calculations, amplifier blocks, active filters, and signal buffering are easily designed with the TLC272 and TLC277. The devices also exhibit low voltage single-supply operation, making them ideally suited for remote and inaccessible battery-powered applications. The common -mode input voltage range includes the negative rail. A wide range of packaging options is available, including small-outline and chip carrier versions for high-density system applications. The device inputs and outputs are designed to withstand -100-mA surge currents without sustaining latch-up. 3 of 4 The TLC272 and TLC277 incorporate internal ESD-protection circuits that prevent functional failures at voltages up to 2000 V as tested under MIL -STD-883C, Method 3015.2; however, care should be exercised in handling these devices as exposure to ESD may result in the degradation of the device parametric performance. The C-suffix devices are characterized for operation from 0°C to 70°C. The I -suffix devices are characterized for operation from -40°C to 85°C. The M-suffix devices are characterized for operation over the full military temperature range of -55°C to 125°C.
