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.

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, T exas 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 (e) CL = 1000 pF, R = 50 Ω (f) CL = 1000 pF, R = 2 kΩ

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.
