MC3303DR2G from onsemi, 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. Class AB output stage; short-circuit protected; typical output impedance 75 ohm at 20 Hz. Swings to within about 1.7 V of VCC and to VEE/GND (with a 10 k pull-down).
2	IN1-	input	Inverting input of amplifier 1. True differential input; typical input bias current -200 nA, input offset current 30 nA, input impedance ~1.0 M-ohm at 20 Hz.
3	IN1+	input	Non-inverting input of amplifier 1. Common-mode input range includes VEE/GND, allowing single-supply use without external biasing.
4	VCC	power_in	Positive supply rail. Single-supply range 3.0 V to 36 V; split-supply range +1.5 V to +18 V. Typical quiescent supply current 2.5-2.8 mA for the whole quad.
5	IN2+	input	Non-inverting input of amplifier 2. Common-mode input range includes the negative supply.
6	IN2-	input	Inverting input of amplifier 2. True differential input; input bias current typ -200 nA.
7	OUT2	output	Output of amplifier 2. Class AB, short-circuit protected; short-circuit current typ +/-30 mA (max +/-45 mA).
8	OUT3	output	Output of amplifier 3. Class AB, short-circuit protected.
9	IN3-	input	Inverting input of amplifier 3.
10	IN3+	input	Non-inverting input of amplifier 3. Common-mode input range includes VEE/GND.
11	VEE/GND	power_in	Negative supply / ground rail. Tied to GND for single-supply operation, or to a negative rail of -1.5 V to -18 V for split-supply operation.
12	IN4+	input	Non-inverting input of amplifier 4.
13	IN4-	input	Inverting input of amplifier 4.
14	OUT4	output	Output of amplifier 4. Class AB, short-circuit protected.
