Changjing · Operational Amplifier · SOP-8

CJ358 from Changjing, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTPUT 1 output Output of op-amp channel 1. Output swings from 0V to VCC-1.5V; source current 20-40mA, sink current 10-20mA at VCC=15V, VO=2V.
2 INPUT 1- input Inverting input of op-amp channel 1. Input bias current ~20nA (typ), input offset current ~5nA. Input voltage range includes ground; do not drive more than 0.3V below GND.
3 INPUT 1+ input Non-inverting input of op-amp channel 1. Input common-mode range 0V to VCC-1.5V; can tolerate up to +32V independent of VCC.
4 GND power_in Ground / negative supply. For single-supply operation tie to 0V; for dual supplies connect to V-.
5 INPUT 2+ input Non-inverting input of op-amp channel 2. Input common-mode range 0V to VCC-1.5V; can tolerate up to +32V independent of VCC.
6 INPUT 2- input Inverting input of op-amp channel 2. Input bias current ~20nA (typ), input offset current ~5nA. Input voltage range includes ground; do not drive more than 0.3V below GND.
7 OUTPUT 2 output Output of op-amp channel 2. Output swings from 0V to VCC-1.5V; source current 20-40mA, sink current 10-20mA at VCC=15V, VO=2V.
8 VCC power_in Positive supply voltage. Single-supply range 3V to 32V (30V recommended max); dual-supply range ±1.5V to ±16V. Supply current 0.5mA (typ) at VCC=5V, 1mA (typ) at VCC=30V.
