OPA2347EA from Texas Instruments, in a SOT-23-8. 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	Out A	output	Output of op-amp channel A. Rail-to-rail output, swings within 5mV of V+ and V-; continuous short-circuit protected.
2	-In A	input	Inverting input of op-amp channel A. Rail-to-rail CMOS input, common-mode range extends 200mV beyond either supply rail.
3	+In A	input	Non-inverting input of op-amp channel A. Rail-to-rail CMOS input, common-mode range extends 200mV beyond either supply rail.
4	V-	power_in	Negative supply rail. Single-supply operation: tie to GND with V+ at 2.3V to 5.5V. Dual-supply operation: ±1.15V to ±2.75V. Absolute max V+ to V- = 7.5V.
5	+In B	input	Non-inverting input of op-amp channel B. Rail-to-rail CMOS input, common-mode range extends 200mV beyond either supply rail.
6	-In B	input	Inverting input of op-amp channel B. Rail-to-rail CMOS input, common-mode range extends 200mV beyond either supply rail.
7	Out B	output	Output of op-amp channel B. Rail-to-rail output, swings within 5mV of V+ and V-; continuous short-circuit protected.
8	V+	power_in	Positive supply rail. 2.3V to 5.5V single-supply, or ±1.15V to ±2.75V dual-supply relative to V-. Absolute max V+ to V- = 7.5V. Quiescent current ~20µA per channel (34µA max).
