Analog Devices · Precision Op Amps · SOIC-8

OP177GSZ from Analog Devices, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOS TRIM passive Optional offset null terminal; a 20 kΩ potentiometer between pins 1 and 8 with its wiper to V- gives a typical ±3 mV trim range.
2 -IN input Inverting input of the amplifier; absolute maximum input voltage ±22 V and differential input ±30 V.
3 +IN input Noninverting input of the amplifier; absolute maximum input voltage ±22 V and differential input ±30 V.
4 V- power_in Negative supply voltage; absolute maximum supply voltage ±22 V.
5 NC unconnected No connect; not internally connected.
6 OUT output Amplifier output with ±13.5 V typical swing into RL ≥ 10 kΩ and indefinite short-circuit duration.
7 V+ power_in Positive supply voltage; absolute maximum supply voltage ±22 V.
8 VOS TRIM passive Optional offset null terminal; a 20 kΩ potentiometer between pins 1 and 8 with its wiper to V- gives a typical ±3 mV trim range.
