description These JFET-input operational amplifiers incorporate well-matched high-voltage JFET and bipolar transistors in a monolithic integrated circuit. They feature low input offset voltage, high slew rate, low input bias and offset currents, and low temperature coefficient of input offset voltage. Offset-voltage adjustment is provided for the TL087 and TL088. The C-suffix devices are characterized for operation from 0°C to 70°C, and 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. AVAILABLE OPTIONS PACKAGE

NOTES: 1. 2. 3. 4.
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. DISSIPATION RATING TABLE PACKAGE

Pulse techniques must be used that will maintain the junction temperature as close to the ambient temperature as possible.

typical values Typical values as presented in this data sheet represent the median (50% point) of device parametric performance.
input bias and offset current At the picoamp bias current level typical of these JFET operational amplifiers, accurate measurement of the bias current becomes difficult. 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 is then 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 are then subtracted algebraically to determine the bias current of the device.

TYPICAL APPLICATION DATA output characteristics All operating characteristics are specified with 100-pF load capacitance. These amplifiers will drive higher capacitive loads; however, as the load capacitance increases, the resulting response pole occurs at lower frequencies, thereby 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).
(a) CL = 100 pF, R = 0
(b) CL = 300 pF, R = 0
(c) CL = 350 pF, R = 0
(d) CL = 1000 pF, R = 0

TYPICAL APPLICATION DATA input characteristics These amplifiers are specified with a minimum and a maximum input voltage that, if exceeded at either input, could cause the device to malfunction. 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 can easily 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. +

noise performance The noise specifications in op amp circuits are greatly dependent on the current in the first-stage diflferential amplifier. The low input bias current requirments 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.
