COS822SR

COSINE · Operational Amplifier · SOIC-8

COS822SR from COSINE, 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 OUTA output Channel A output; swings to within millivolts of each supply rail (typ. 8mV at RL=10kΩ).
2 -IN1 input Channel A inverting input; voltage range -Vs -0.3V to +Vs +0.3V.
3 +IN1 input Channel A non-inverting input; same voltage range as -IN.
4 -Vs power_in Negative power supply or ground; bypass with 0.1µF close to the part if not grounded.
5 +IN2 input Channel B non-inverting input; same voltage range as -IN.
6 -IN2 input Channel B inverting input; voltage range -Vs -0.3V to +Vs +0.3V.
7 OUTB output Channel B output; swings to within millivolts of each supply rail (typ. 8mV at RL=10kΩ).
8 +Vs power_in Positive power supply, 1.8V to 5.5V; place a 0.1µF bypass capacitor close to the pin.
