OPA2347UA from UMW, 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	OUTA	output	Amplifier A output. Rail-to-rail output stage; swings within 5mV of the supply rails with a 100kΩ load. Short-circuit current ±17mA typ.
2	-IN A	input	Amplifier A inverting input. Rail-to-rail CMOS input; common-mode range extends from (V-)-0.2V to (V+)+0.2V. Input bias current ±0.5pA typ.
3	+IN A	input	Amplifier A non-inverting input. Rail-to-rail CMOS input; common-mode range extends from (V-)-0.2V to (V+)+0.2V.
4	V-	power_in	Negative supply / ground. Total supply (V+)-(V-) between 2.3V (min operating) and 5.5V; absolute max 7.5V. Quiescent current 20µA typ per amplifier.
5	+IN B	input	Amplifier B non-inverting input. Rail-to-rail CMOS input; common-mode range extends from (V-)-0.2V to (V+)+0.2V.
6	-IN B	input	Amplifier B inverting input. Rail-to-rail CMOS input; common-mode range extends from (V-)-0.2V to (V+)+0.2V.
7	OUTB	output	Amplifier B output. Rail-to-rail output stage; swings within 5mV of the rails with a 100kΩ load. Short-circuit current ±17mA typ.
8	V+	power_in	Positive supply. Single-supply operation 2.3V to 5.5V (dual supply supported). Absolute max (V+)-(V-) = 7.5V. Decouple locally with a ceramic capacitor.
