WS72324S-14 from WILLSEMI Will Semicon, 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	Output of op-amp channel A. Rail-to-rail output swing, drives 2 kΩ loads, short-circuit current 43 mA source / 47 mA sink typical.
2	-INA	input	Inverting input of op-amp channel A. Rail-to-rail input; common-mode range (V-)-0.2 V to (V+)+0.2 V. Input bias current 10 pA typical.
3	+INA	input	Non-inverting input of op-amp channel A. Rail-to-rail input; common-mode range (V-)-0.2 V to (V+)+0.2 V.
4	V+	power_in	Positive supply. Single-supply range 1.8 V to 5.5 V (absolute max V+ minus V- = 6 V). Shared by all four amplifiers.
5	+INB	input	Non-inverting input of op-amp channel B. Rail-to-rail input; common-mode range (V-)-0.2 V to (V+)+0.2 V.
6	-INB	input	Inverting input of op-amp channel B. Rail-to-rail input; input bias current 10 pA typical.
7	OUTB	output	Output of op-amp channel B. Rail-to-rail output swing, drives 2 kΩ loads.
8	OUTC	output	Output of op-amp channel C. Rail-to-rail output swing, drives 2 kΩ loads.
9	-INC	input	Inverting input of op-amp channel C. Rail-to-rail input.
10	+INC	input	Non-inverting input of op-amp channel C. Rail-to-rail input; common-mode range (V-)-0.2 V to (V+)+0.2 V.
11	V-	power_in	Negative supply / ground return. Tie to GND for single-supply operation, or to a negative rail for dual-supply operation (V+ - V- ≤ 6 V).
12	+IND	input	Non-inverting input of op-amp channel D. Rail-to-rail input; common-mode range (V-)-0.2 V to (V+)+0.2 V.
13	-IND	input	Inverting input of op-amp channel D. Rail-to-rail input; input bias current 10 pA typical.
14	OUTD	output	Output of op-amp channel D. Rail-to-rail output swing, drives 2 kΩ loads.
