Improvements have been made over OP-O7 specifications in
several areas. Notable is bias current, which remains below
250pA over the full military temperature range. The OP-97 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 OP-97, at 114dB minimum over wider ranges
of common-mode or supply voltage. Outstanding PSR, a
supply range specified from i2.25V to iZOV and the C)P-97's
minimal power requirements combine to make the OP-97 a
preferred device for portable and battery-powered instruments.
The OP-97 conforms to the OP-07 pinout, with the null
potentiometer connected between pins 1 and 8 with the wiper
to V+. The OP-97 will upgrade circuit designs using 725, OP05,
OP07, OP12, and 1012 type amplifiers. It may replace 741-type
amplifiers in circuits without nulling or where the nulling
circuitry has been removed.

NOTES:
1. Absolute maximum ratings apply to both DICE and packaged parts, unless
otherwise noted.
2 IV is specified for worst case mounting conditions, i.e., A, is specified for
device in socket for TO, CerDlP. and P-DlP packages: 61A is specified for
device soldered to printed circuit board for so package.
3. For supply voltages less than =20V, the absolute maximum input voltage is
equal to the supply voltage.
4. The OP-97's inputs are protected by back-to-back diodes. Current-limiting re-
sistors are not used in order to achieve low noise. Differential input voltages
greater than 1V will cause excessive current to flow through the input Protec-
tion diodes unless limiting resistance is used.
