Theselow offset voltages generally eliminate any need for external null-ing. The OP07 also features low input bias current (±4 nA forOP07E) and high open-loop gain (200 V/mV for OP07E). Thelow offsets and high open-loop gain make the OP07 particularlyuseful for high-gain instrumentation applications.The wide input voltage range of ±13 V minimum combined withhigh CMRR of 106 dB (OP07E) and high input impedace pro-vides high accuracy in the noninverting circuit configuration.Excellent linearity and gain accuracy can be maintained even athigh closed-loop gains. Stability of offsets and gain with time orvariations in temperature is excellent. The accuracy and stabilityof the OP07, even at high gain, combined with the freedomfrom external nulling have made the OP07 an industry standardfor instrumentation applications.The OP07 is available in two standard performance grades. TheOP07E is specified for operation over the 0°C to 70°C range, andOP07C over the –40°C to +85°C temperature range.The OP07 is available in epoxy 8-lead Mini-DIP and 8-lead SOIC.It is a direct replacement for 725,108A, and OP05 amplifiers;741-types may be directly replaced by removing the 741’s nullingpotentiometer. For improved specifications, see the OP177 orOP1177. For ceramic DIP and TO-99 packages and standardmicro circuit (SMD) versions, see the OP77.Figure 1.
