GENERAL DESCRIPTION

The OP97 is a low power alternative to the industry-standard

OP07 precision amplifier. The OP97 maintains the standards of

performance set by the OP07 while utilizing only 600 µA supply

current, less than 1/6 that of an OP07. Offset voltage is an ultralow

25 µV, and drift over temperature is below 0.6 µV/°C. External

offset trimming is not required in the majority of circuits.

Improvements have been made over OP07 specifications in

several areas. Notable is bias current, which remains below 250

pA over the full military temperature range. The OP97 is ideal

for use in precision long-term integrators or sample-and-hold

circuits that must operate at elevated temperatures.

FEATURES

Low Supply Current: 600 A Max

OP07 Type Performance

Very Low Bias Current

High Common-Mode Rejection: 114 dB Min

Extended Industrial Temperature Range: –40 C to +85 C

Offset Voltage: 20 V Max

Offset Voltage Drift: 0.6 V/ C Max

25 C: 100 pA Max

–55 C to +125 C: 250 pA Max

Common-mode rejection and power supply rejection are also

improved with the OP97, at 114 dB minimum over wider ranges

of common-mode or supply voltage. Outstanding PSR, a supply

range specified from ± 2.25 V to ± 20 V and the OP97’s minimal

power requirements combine to make the OP97 a preferred

device for portable and battery-powered instruments.

The OP97 conforms to the OP07 pinout, with the null potenti-

ometer connected between Pins 1 and 8 with the wiper to V+.

The OP97 will upgrade circuit designs using 725, OP05, OP07,

OP12, and 1012 type amplifiers. It may replace 741-type ampli-

fiers in circuits without nulling or where the nulling circuitry has

been removed.
