COSOP27SRA from COSINE, 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	NC/TRIM	passive	Labelled NC in the pin diagram; the pin function table also describes an optional VOS trim pin with an offset nulling resistor (e.g. 20kΩ) placed between pins 1 and 8.
2	-IN	input	Inverting input of the amplifier, with a voltage range from -Vs to +Vs.
3	+IN	input	Non-inverting input of the amplifier, with the same voltage range as -IN.
4	-Vs	power_in	Negative power supply or ground; if not connected to ground, bypass it with a 0.1µF capacitor placed as close to the part as possible.
5	NC	unconnected	No connection.
6	OUT	output	Amplifier output, whose voltage range extends to within millivolts of each supply rail.
7	+Vs	power_in	Positive power supply; place a 0.1µF bypass capacitor as close to the part as possible between the supply pins or between the supply pins and ground.
8	NC/TRIM	passive	Labelled NC in the pin diagram; the pin function table also describes an optional VOS trim pin with an offset nulling resistor (e.g. 20kΩ) placed between pins 1 and 8.
