OP07

Texas Instruments · Operational Amplifier · SOIC-8

The OP07 is a precision operational amplifier with low input offset voltage (75 uV typ), low offset drift, and low noise. Internal trimming removes the need for external null components, making it a straightforward choice for high-accuracy instrumentation, active filters, and sensor signal conditioning.

Pinout

Pin Name Type Function
1 OFFSET N1 input External input offset voltage adjustment. Connect a 10-20 kΩ potentiometer between OFFSET N1 (pin 1) and OFFSET N2 (pin 8) with the wiper to V- to trim residual input offset voltage.
2 IN- input Inverting input of the operational amplifier. High-impedance bipolar input; keep source-impedance matching with IN+ to minimize offset drift from input bias current.
3 IN+ input Noninverting input of the operational amplifier. Common-mode input range typically 0 V to ±14 V at ±15 V supply; recommended VCM is -13 V to 13 V.
4 V- power_in Negative supply rail. Dual-supply range ±3 V to ±18 V; single-supply operation 6 V to 36 V referenced to V+ with V- at ground.
5 NC unconnected No internal connection. Leave floating or tie to a nearby quiet net; do not connect to any active signal.
6 OUT output Amplifier output. Continuous short-circuit safe to ground or V-; fast-ramping shorts to V+ can damage the device.
7 V+ power_in Positive supply rail. Dual-supply range ±3 V to ±18 V (max ±22 V absolute); bypass to V- with a 100 nF ceramic capacitor located close to the pin.
8 OFFSET N2 input External input offset voltage adjustment. Paired with OFFSET N1 (pin 1) across a 10-20 kΩ potentiometer whose wiper returns to V- for trimming input offset voltage.
