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 A supply
current, less than 1/6 that of an OP07. Offset voltage is an
ultralow 25 V, and drift over temperature is below 0.6 V/ 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
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.
