LM2902DT from STMicroelectronics, in a SOIC-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 op-amp 1. Push-pull class-AB output; short-circuit protected (~20 mA typical short-circuit current). VOH reaches VCC+ - 1.5 V (VCC+ = 5 V, RL = 2 kΩ) up to VCC+ - 3 V approx.
2	IN1-	input	Inverting input of op-amp 1. High-impedance PNP input; input bias current ~20 nA typ (150 nA max at 25 °C). Common-mode range includes the negative rail down to VCC-.
3	IN1+	input	Non-inverting input of op-amp 1. High-impedance PNP input; common-mode range extends from VCC- (negative rail) to (VCC+) - 1.5 V.
4	VCC+	power_in	Positive supply rail, shared by all four op-amps. Operating range 3 V to 30 V single-supply (or ±1.5 V to ±15 V split); absolute maximum ±16 to 32 V. Total quiescent current ~0.7 mA (VCC+ = 5 V) to 1.5 mA (VCC+ = 30 V) with no load.
5	IN2+	input	Non-inverting input of op-amp 2. Same characteristics as other non-inverting inputs; common-mode range includes VCC-.
6	IN2-	input	Inverting input of op-amp 2. Input bias current ~20 nA typ.
7	OUT2	output	Output of op-amp 2. Class-AB output stage, short-circuit protected, sinks ~20 mA typ, sources ~40 mA typ.
8	OUT3	output	Output of op-amp 3. Class-AB output stage, short-circuit protected.
9	IN3-	input	Inverting input of op-amp 3.
10	IN3+	input	Non-inverting input of op-amp 3.
11	VCC-	power_in	Negative supply / ground. Typically tied to GND in single-supply operation, or to the negative rail in split-supply operation. Common-mode input range includes this rail.
12	IN4+	input	Non-inverting input of op-amp 4.
13	IN4-	input	Inverting input of op-amp 4.
14	OUT4	output	Output of op-amp 4. Class-AB output stage, short-circuit protected.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm2902dt.step`	195 KB	You want the bare part, or you mark your own boards.
`lm2902dt-etched.step`	2.0 MB	You want the part with `LM2902DT` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 503 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
