LM2902M from HGSEMI, 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	OUT1	output	Output of amplifier 1. Push-pull output; short-circuit current ~40 mA at VCC = +15V.
2	IN1-	input	Inverting input of amplifier 1. Input bias current typ. 20 nA; common-mode range includes ground.
3	IN1+	input	Non-inverting input of amplifier 1. Input common-mode range 0V to VCC−1.5V.
4	VCC+	power_in	Positive supply. Single supply +3V to +30V, or split supply +1.5V to +15V. Absolute max ±16 to 32V.
5	IN2+	input	Non-inverting input of amplifier 2.
6	IN2-	input	Inverting input of amplifier 2.
7	OUT2	output	Output of amplifier 2.
8	OUT3	output	Output of amplifier 3.
9	IN3-	input	Inverting input of amplifier 3.
10	IN3+	input	Non-inverting input of amplifier 3.
11	VCC-	power_in	Negative supply / ground. Tied to GND for single-supply operation, or to negative rail for split-supply.
12	IN4+	input	Non-inverting input of amplifier 4.
13	IN4-	input	Inverting input of amplifier 4.
14	OUT4	output	Output of amplifier 4.
