OP27EM

HGSEMI · Operational Amplifier · SOP-8

OP27EM from HGSEMI, in a SOP-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 Input offset voltage trim terminal; a 20kΩ potentiometer is connected between pins 1 and 8 with its wiper to V+ (VCC+).
2 -IN input Inverting input of the amplifier, with input voltage range of ±13V and absolute maximum input voltage of ±18V.
3 +IN input Non-inverting input of the amplifier, with input voltage range of ±13V and absolute maximum input voltage of ±18V.
4 V- power_in Negative supply voltage (VCC-), operating range ±3V to ±18V, absolute maximum ±18V.
5 NC unconnected No connect; not internally connected.
6 OUT output Amplifier output, with peak swing of ±12V into 10kΩ and ±11.5V into 2kΩ at VCC=±15V.
7 V+ power_in Positive supply voltage (VCC+), operating range ±3V to ±18V, absolute maximum ±18V.
8 VOS TRIM passive Input offset voltage trim terminal; a 20kΩ potentiometer is connected between pins 1 and 8 with its wiper to V+ (VCC+).
