The OP97 is a low power alternative to the industry-standard Common-mode rejection and power supply rejection are also OP07 precision amplifier. The OP97 maintains the standards of improved with the OP97, at 114 dB minimum over wider performance set by the OP07 while utilizing only 600 μA supply ranges of common-mode or supply voltage. Outstanding PSR, a current, less than 1/6 that of an OP07. Offset voltage is an ultralow supply range specified from ±2.25 V to ±20 V, and the minimal 25 μV, and drift over temperature is below 0.6 μV/°C. External power requirements of the OP97 combine to make the OP97 a offset trimming is not required in the majority of circuits. preferred device for portable and battery-powered instruments. Improvements have been made over OP07 specifications in The OP97 conforms to the OP07 pinout, with the null potenti- several areas. Notable is bias current, which remains below ometer connected between Pin 1 and Pin 8 with the wiper to 250 pA over the full military temperature range. The OP97 is V+. The OP97 upgrades circuit designs using AD725, OP05, ideal for use in precision long-term integrators or sample-and- OP07, OP12, and PM1012 type amplifiers. It may replace 741- hold circuits that must operate at elevated temperatures. type amplifiers in circuits without nulling or where the nulling circuitry has been removed.
