OPA4347UA from UMW, in a SOP-14. 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; swings within ~5 mV of V+/V- into 100 kΩ. Short-circuit current ±17 mA (typ).
2	-INA	input	Amplifier A inverting input. Rail-to-rail input, extends 200 mV beyond supplies. Bias current ±0.5 pA (typ).
3	+INA	input	Amplifier A non-inverting input. Rail-to-rail input, extends 200 mV beyond supplies.
4	V+	power_in	Positive supply. Single-supply range 2.3 V to 5.5 V (specified 2.5-5.5 V). Total V+ − V− must not exceed 7.5 V.
5	+INB	input	Amplifier B non-inverting input. Rail-to-rail input.
6	-INB	input	Amplifier B inverting input. Rail-to-rail input.
7	OUTB	output	Amplifier B output. Rail-to-rail.
8	OUTC	output	Amplifier C output. Rail-to-rail.
9	-INC	input	Amplifier C inverting input. Rail-to-rail input.
10	+INC	input	Amplifier C non-inverting input. Rail-to-rail input.
11	V-	power_in	Negative supply / ground for single-supply operation. Absolute maximum V+ − V− = 7.5 V.
12	+IND	input	Amplifier D non-inverting input. Rail-to-rail input.
13	-IND	input	Amplifier D inverting input. Rail-to-rail input.
14	OUTD	output	Amplifier D output. Rail-to-rail.
