All voltage values, except differential voltages, are with respect to the midpoint between VCC+ and VCC−. Differential voltages are at the noninverting input terminal with respect to the inverting input terminal. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less. The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded. Maximum power dissipation is a function of TJ(max), qJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/qJA. Operating at the absolute maximum TJ of 150°C can affect reliability.

Not only does this measurement require a picoammeter, but test socket leakages can easily exceed the actual device bias currents. To accurately measure these small currents, Texas Instruments uses a two-step process. The socket leakage is measured using picoammeters with bias voltages applied, but with no device in the socket. The device then is inserted in the socket and a second test that measures both the socket leakage and the device input bias current is performed. The two measurements then are subtracted algebraically to determine the bias current of the device. 6 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 TL087, TL088, TL287, TL288 JFET-INPUT OPERATIONAL AMPLIFIERS SLOS082B – MARCH 1979 – REVISED – JULY 2004 TYPICAL CHARACTERISTICS table of graphs FIGURE α VIO Temperature coefficient of input offset voltage Distribution IIO Input offset current vs Temperature 8 IIB Input bias current vs VIC vs Temperature 9 8 VI Common-mode input voltage range limits vs VCC vs Temperature 10 11 VID Differential input voltage vs Output voltage 12 VOM Maximum peak output voltage swing vs VCC vs Output current vs Frequency vs Temperature 13 17 14, 15, 16 18 AVD Differential voltage amplification vs RL vs Frequency vs Temperature 19 20 21 Output impedance vs Frequency 24 CMRR Common-mode rejection ratio vs Frequency vs Temperature 22 23 kSVR Supply-voltage rejection ratio vs Temperature 25 IOS Short-circuit output current vs VCC vs Time vs Temperature 26 27 28 ICC Supply current vs VCC vs Temperature 29 30 SR Slew rate vs RL vs Temperature 31 32 Overshoot factor vs CL 33 Equivalent input noise voltage vs Frequency 34 Total harmonic distortion vs Frequency 35 B1 Unity-gain bandwidth vs VCC vs Temperature 36 37 φm Phase margin vs VCC vs CL vs Temperature 38 39 40 Phase shift vs Frequency 20 Pulse response Small-signal Large-signal 41 42 zo Vn THD POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 6, 7 7 TL087, TL088, TL287, TL288 JFET-INPUT OPERATIONAL AMPLIFIERS SLOS082B – MARCH 1979 – REVISED – JULY 2004 TYPICAL CHARACTERISTICS† DISTRIBUTION OF TL088 INPUT OFFSET VOLTAGE TEMPERATURE COEFFICIENT DISTRIBUTION OF TL288 INPUT OFFSET VOLTAGE TEMPERATURE COEFFICIENT 20 20 Percentage of Amplifiers − % Percentage of Units − % 16 120 Units Tested From 2 Wafer Lots VCC ± = ± 15 V TA = 25°C to 125°C P Package 12 8 15 172 Amplifiers Tested From 2 Wafer Lots VCC ± = ± 15 V TA = 25°C to 125°C P Package One unit at − 34.6 μV/°C 10 5 4 0 −25 −20 −15 −10 −5 0 5 10 15 20 0 −30 25 αVIO − Temperature Coefficient − μV/°C 30 −20 −10 0 10 20 αVIO − Temperature Coefficient − μV/°C Figure 6 Figure 7 INPUT BIAS CURRENT AND INPUT OFFSET CURRENT vs FREE-AIR TEMPERATURE ÁÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁÁ 100 10 VCC ± = ± 15 V VO = 0 VIC = 0 10 VCC ± = ± 15 V TA = 25°C IIB I IB − Input Bias Current − nA IIIB IIO − Bias and Offset Currents − nA IB and IIO INPUT BIAS CURRENT vs COMMON-MODE INPUT VOLTAGE I IB 1 IIO 0.1 5 0 −5 0.01 0.001 25 45 65 85 105 125 −10 −15 −10 TA − Free-Air Temperature − °C Figure 8 † 8 −5 0 5 10 VIC − Common-Mode Input Voltage − V Figure 9 Data at high and low temperatures are applicable within the rated operating free-air temperature ranges of the various devices.

These amplifiers will drive higher capacitive loads; however, as the load capacitance increases, the resulting response pole occurs at lower frequencies, causing ringing, peaking, or even oscillation. The value of the load capacitance at which oscillation occurs varies with production lots. If an application appears to be sensitive to oscillation due to load capacitance, adding a small resistance in series with the load should alleviate the problem. Capacitive loads of 1000 pF, and larger, may be driven if enough resistance is added in series with the output (see Figure 43).

Because of the extremely high input impedance and resulting low bias current requirements, these amplifiers are well suited for low-level signal processing; however, leakage currents on printed circuit boards and sockets easily can exceed bias current requirements and cause degradation in system performance. It is good practice to include guard rings around inputs (see Figure 45). These guards should be driven from a low-impedance source at the same voltage level as the common-mode input. + − VO + (a) NONINVERTING AMPLIFIER VI (b) INVERTING AMPLIFIER + VI − VO − VI VO (c) UNITY−GAIN AMPLIFIER Figure 45. Use of Guard Rings noise performance The noise specifications in operational amplifier circuits are greatly dependent on the current in the first-stage diflferential amplifier. The low input bias current requirements of these amplifiers result in a very low current noise. This feature makes the devices especially favorable over bipolar devices when using values of circuit impedance greater than 50 kΩ.
