GN358A

GN Semic · Operational Amplifier · SOP-8

GN358A from GN Semic, 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 1OUT output Output of op-amp 1 (channel 1 of the two independent high-gain amplifiers); the datasheet gives no output-swing or drive limit for this pin alone.
2 1IN- input Inverting input of op-amp 1; the input voltage range is -0.3 V to VCC, and input current is limited to 50 mA when VIN is below -0.3 V.
3 1IN+ input Non-inverting input of op-amp 1; the input voltage range is -0.3 V to VCC, and input current is limited to 50 mA when VIN is below -0.3 V.
4 GND power_in Ground reference pin shared by both amplifiers, used as the 0 V reference for single-supply and split-supply operation.
5 2IN+ input Non-inverting input of op-amp 2; the input voltage range is -0.3 V to VCC, and input current is limited to 50 mA when VIN is below -0.3 V.
6 2IN- input Inverting input of op-amp 2; the input voltage range is -0.3 V to VCC, and input current is limited to 50 mA when VIN is below -0.3 V.
7 2OUT output Output of op-amp 2 (channel 2 of the two independent high-gain amplifiers); the datasheet gives no output-swing or drive limit for this pin alone.
8 VCC power_in Positive supply pin; single-supply operation is 4 V to 24 V, or split supply ±2 V to ±12 V, with absolute maximum differential input voltage of 24 V.
