FEATURES

Low supply current: 600 μA maximum

OP07 type performance

Very low bias current

High common-mode rejection: 114 dB minimum

Extended industrial temperature range: −40°C to +85°C

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.

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 minimal

power requirements of the OP97 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 Pin 1 and Pin 8 with the wiper to

V+. The OP97 upgrades circuit designs using AD725, OP05,

OP07, OP12, and PM1012 type amplifiers. It may replace 741-

type amplifiers in circuits without nulling or where the nulling

circuitry has been removed.
