IDD < 1 µA Available in Q-Temp Automotive High Reliability Automotive Applications Configuration Control / Print Support Qualification to Automotive Standards description The TLV277x CMOS operational amplifier family combines high slew rate and bandwidth, rail-to-rail output swing, high output drive, and excellent dc precision. The device provides 10.5 V/µs of slew rate and 5.1 MHz of bandwidth while only consuming 1 mA of supply current per channel. This ac performance is much higher than current competitive CMOS amplifiers. The rail-to-rail output swing and high output drive make these devices a good choice for driving the analog input or reference of analog-to-digital converters. These devices also have low distortion while driving a 600-Ω load for use in telecom systems. These amplifiers have a 360-µV input offset voltage, a 17 nV/√Hz input noise voltage, and a 2-pA input bias current for measurement, medical, and industrial applications. The TLV277x family is also specified across an extended temperature range (−40°C to 125°C), making it useful for automotive systems, and the military temperature range (−55°C to 125°C), for military systems. These devices operate from a 2.5-V to 5.5-V single supply voltage and are characterized at 2.7 V and 5 V. The single-supply operation and low power consumption make these devices a good solution for portable applications. The following table lists the packages available.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, except differential voltages, are with respect to GND . 2. Differential voltages are at the noninverting input with respect to the inverting input. Excessive current flows when input is brought below GND − 0.3 V. 3. The output may be shorted to either supply. Temperature and /or supply voltages must be limited to ensure that the maximum dissipation rating is not exceeded.

amplifier is configured in this manner, capacitive loading directly on the output will decrease the device’s phase margin leading to high frequency ringing or oscillations. Therefore, for capacitive loads of greater than 10 pF, it is recommended that a resistor be placed in series (RNULL) with the output of the amplifier, as shown in Figure 58.

The ACH04-08-05 is a shock sensor designed to convert mechanical acceleration into electrical signals. The sensor contains three piezoelectric sensing elements oriented to simultaneously measure acceleration in three orthogonal, linear axes (x, y, z). The operating frequency is 0.5 Hz to 5 kHz. The output is buffered with an internal JFET and has a typical output voltage of 1.80 mV/g for the x and y axis and 1.35 mV/g for the z axis. Amplification and frequency shaping of the shock sensor output is done by the TLV2772 rail-to-rail operational amplifier. The TLV2772 is ideal for this application as it offers high input impedance, good slew rate, and excellent dc precision. The rail-to-rail output swing and high output drive are perfect for driving the analog input of the TLV1544 ADC. 1.23 V C2 2.2 nF R3 10 kΩ R4 100 kΩ 3V R2 1 MΩ 1 Axis ACH04−08−05 3V C1 0.22 µF + 3 _ 1 4 R1 100 kΩ R5 1 kΩ 8 2 1/2 TLV2772 C3 0.22 µF Signal Conditioning 3V R6 2.2 kΩ 1.23 V Shock Sensor Output to TLV1544 (ADC) 1.23 V C R TLV431 A Voltage Reference Figure 62. Accelerometer Interface Schematic The sensor signal must be amplified and frequency-shaped to provide a signal the ADC can properly convert into the digital domain. Figure 62 shows the topology used in this application for one axis of the sensor. This system is powered from a single 3-V supply. Configuring the TLV431 with a 2.2-kΩ resistor produces a reference voltage of 1.23 V. This voltage is used to bias the operational amplifier and the internal JFETs in the shock sensor. 36 WWW.TI.COM                      SLOS209G − JANUARY 1998 − REVISED FEBRUARY 2004 APPLICATION INFORMATION gain calculation Since the TLV2772 is capable of rail-to-rail output using a 3-V supply, VO = 0 (min) to 3 V (max). With no signal from the sensor, nominal VO = reference voltage = 1.23 V. Therefore, the maximum negative swing from nominal is 0 V − 1.23 V = −1.23 V and the maximum positive swing is 3 V − 1.23 V = 1.77 V. By modeling the shock sensor as a low impedance voltage source with output of 2.25 mV/g (max) in the x and y axis and 1.70 mV/g (max) in the z axis, the gain of the circuit is calculated by equation 1. Gain + Output Swing Sensor Signal Acceleration (1) To avoid saturation of the operational amplifier, the gain calculations are based on the maximum negative swing of −1.23 V and the maximum sensor output of 2.25 mV/g (x and y axis) and 1.70 mV/g (z axis). Gain (x, y) + * 1.23 V + 10.9 2.25 mVńg * 50 g (2) and Gain (z) + –1.23 V + 14.5 1.70 mVńg –50 g (3) By selecting R3 = 10 kΩ and R4 = 100 kΩ, in the x and y channels, a gain of 11 is realized. By selecting R3 = 7.5 kΩ and R4 = 100 kΩ, in the z channel, a gain of 14.3 is realized. The schematic shows the configuration for either the x- or y-axis. bandwidth calculation To calculate the component values for the frequency shaping characteristics of the signal conditioning circuit, 1 Hz and 500 Hz are selected as the minimum required 3-dB bandwidth. To minimize the value of the input capacitor (C1) required to set the lower cutoff frequency requires a large value resistor for R2 is required. A 1-MΩ resistor is used in this example. To set the lower cutoff frequency, the required capacitor value for C1 is: C1 + 1 + 0.159 µF 2p f LOW R 2 (4) Using a value of 0.22 µF, a more common value of capacitor, the lower cutoff frequency is 0.724 Hz. To minimize the phase shift in the feedback loop caused by the input capacitance of the TLV2772, it is best to minimize the value of the feedback resistor R4. However, to reduce the required capacitance in the feedback loop a large value for R4 is required. Therefore, a compromise for the value of R4 must be made. In this circuit, a value of 100 kΩ has been selected. To set the upper cutoff frequency, the required capacitor value for C2 is: C2 + 1 + 3.18 µF 2p f HIGH R 4 (5) Using a 2.2-nF capacitor, the upper cutoff frequency is 724 Hz. R5 and C3 also cause the signal response to roll off. Therefore, it is beneficial to design this roll-off point to begin at the upper cutoff frequency. Assuming a value of 1 kΩ for R5, the value for C3 is calculated to be 0.22 µF.

A general set of guidelines is given in the following. D Ground planes—It is highly recommended that a ground plane be used on the board to provide all components with a low inductive ground connection. However, in the areas of the amplifier inputs and output, the ground plane can be removed to minimize the stray capacitance. D Proper power supply decoupling—Use a 6.8-µF tantalum capacitor in parallel with a 0.1-µF ceramic capacitor on each supply terminal. It may be possible to share the tantalum among several amplifiers depending on the application, but a 0.1-µF ceramic capacitor should always be used on the supply terminal of every amplifier. In addition, the 0.1-µF capacitor should be placed as close as possible to the supply terminal. As this distance increases, the inductance in the connecting trace makes the capacitor less effective. The designer should strive for distances of less than 0.1 inches between the device power terminals and the ceramic capacitors. D Sockets—Sockets can be used but are not recommended. The additional lead inductance in the socket pins will often lead to stability problems. Surface-mount packages soldered directly to the printed-circuit board is the best implementation. D Short trace runs/compact part placements—Optimum high performance is achieved when stray series inductance has been minimized. To realize this, the circuit layout should be made as compact as possible, thereby minimizing the length of all trace runs. Particular attention should be paid to the inverting input of the amplifier. Its length should be kept as short as possible. This will help to minimize stray capacitance at the input of the amplifier. D Surface-mount passive components—Using surface-mount passive components is recommended for high performance amplifier circuits for several reasons. First, because of the extremely low lead inductance of surface-mount components, the problem with stray series inductance is greatly reduced. Second, the small size of surface-mount components naturally leads to a more compact layout thereby minimizing both stray inductance and capacitance. If leaded components are used, it is recommended that the lead lengths be kept as short as possible. 38 WWW.TI.COM                      SLOS209G − JANUARY 1998 − REVISED FEBRUARY 2004 APPLICATION INFORMATION general power dissipation considerations For a given θJA, the maximum power dissipation is shown in Figure 63 and is calculated by the following formula: P D + Where: ǒ T Ǔ –T MAX A q JA PD = Maximum power dissipation of TLV277x IC (watts) TMAX = Absolute maximum junction temperature (150°C) TA = Free-ambient air temperature (°C) θJA = θJC + θCA θJC = Thermal coefficient from junction to case θCA = Thermal coefficient from case to ambient air (°C/W) MAXIMUM POWER DISSIPATION vs FREE-AIR TEMPERATURE 2 Maximum Power Dissipation − W 1.75 1.5 1.25 TJ = 150°C PDIP Package Low-K Test PCB θJA = 104°C/W SOIC Package Low-K Test PCB θJA = 176°C/W MSOP Package Low-K Test PCB θJA = 260°C/W 1 0.75 0.5 0.25 SOT-23 Package Low-K Test PCB θJA = 324°C/W 0 −55 −40 −25 −10 5 20 35 50 65 80 95 110 125 TA − Free-Air Temperature − °C NOTE A: Results are with no air flow and using JEDEC Standard Low-K test PCB.

When the shutdown terminal is tied low, the supply current is reduced to 0.8 µA/channel, the amplifier is disabled, and the outputs are placed in a high impedance mode. To enable the amplifier, the shutdown terminal can either be left floating or pulled high. When the shutdown terminal is left floating, care needs to be taken to ensure that parasitic leakage current at the shutdown terminal does not inadvertently place the operational amplifier into shutdown. The shutdown terminal threshold is always referenced to VDD/2. Therefore, when operating the device with split supply voltages (e.g. ± 2.5 V), the shutdown terminal needs to be pulled to VDD− (not GND) to disable the operational amplifier. The amplifier’s output with a shutdown pulse is shown in Figures 48, 49, and 50. The amplifier is powered with a single 5-V supply and configured as a noninverting configuration with a gain of 5. The amplifier turnon and turnoff times are measured from the 50% point of the shutdown pulse to the 50% point of the output waveform. The times for the single, dual, and quad are listed in the data tables. The bump on the rising edge of the TLV2770 output waveform is due to the start-up circuit on the bias generator. For the dual and quad (TLV2773/5), this bump is attributed to the bias generator’s start-up circuit as well as the crosstalk between the other channel(s), which are in shutdown. Figures 55 and 56 show the amplifier’s forward and reverse isolation in shutdown. The operational amplifier is powered by ±1.35-V supplies and configured as a voltage follower (AV = 1). The isolation performance is plotted across frequency for both 0.1 VPP and 2.7 VPP input signals. During normal operation, the amplifier would not be able to handle a 2.7-VPP input signal with a supply voltage of ±1.35 V since it exceeds the common-mode input voltage range (VICR). However, this curve illustrates that the amplifier remains in shutdown even under a worst case scenario. 40 WWW.TI.COM                      SLOS209G − JANUARY 1998 − REVISED FEBRUARY 2004 APPLICATION INFORMATION macromodel information Macromodel information provided was derived using Microsim Parts Release 8, the model generation software used with Microsim PSpice .
