OP97AJ

The OP97AJ belongs to OP-97 family which is a low-power alternative to the industry-standard OP-07 precision amplifier which is ideal for use in precision long-term integrators or sample-and- hold circuits that must operate at elevated temperatures. The OP-97 maintains the standards of performance set by the OP-07 while utilizing only 600A supply current, less than 1 /6 that of an OP-07. Offset voltage is an ultra-low 25V, and drift overtemperature is below 0.6V/°C. 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 pulling or where the pulling circuitry has been removed. External offsettrimming is not required in the majority of circuits Improvements have been made over OP-07 specifications in several areas. Notable is bias current, which remains below 250pA over the full military temperature range. 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±2.25V to±20V and the OP-9Ts 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 absolute maximum ratings of OP97AJ are (1)supply voltage: ±120 V; (2)input voltage (Note 3 For supply voltages less than ±20V, the absolute maximum input voltage is equal to the supply voltage): ±120 V; (3)differential input voltage (Note 4: The OP-97's inputs are protected by back-to-back diodes. Current-limiting resistors are not used in order to achieve low noise. Differential input voltages greater than 1 V will cause excessive current to flow through the input proteo- tion diodes unless limiting resistance is used.): ±1V; (4)differential input current (Note 4: The OP-97's inputs are protected by back-to-back diodes.
