LM2902DR 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	1OUT	output	Output of op-amp channel 1. High-level output voltage typically Vcc-1.5V (RL=2kΩ); low-level typically 5 mV (RL≤10kΩ).
2	1IN-	input	Inverting (negative) input of op-amp channel 1. Common-mode input range 0 to Vcc-2 V; input bias current typically -20 nA.
3	1IN+	input	Non-inverting (positive) input of op-amp channel 1. Common-mode input range 0 to Vcc-2 V; input bias current typically -20 nA.
4	VCC	power_in	Positive supply voltage. Single-supply operation 3V to 26V (LM2902); dual supply ±1.5V to ±13V. Absolute maximum 26V.
5	2IN+	input	Non-inverting (positive) input of op-amp channel 2. Common-mode input range 0 to Vcc-2 V.
6	2IN-	input	Inverting (negative) input of op-amp channel 2. Common-mode input range 0 to Vcc-2 V.
7	2OUT	output	Output of op-amp channel 2. High-level output voltage typically Vcc-1.5V (RL=2kΩ); low-level typically 5 mV (RL≤10kΩ).
8	3OUT	output	Output of op-amp channel 3. High-level output voltage typically Vcc-1.5V (RL=2kΩ); low-level typically 5 mV (RL≤10kΩ).
9	3IN-	input	Inverting (negative) input of op-amp channel 3. Common-mode input range 0 to Vcc-2 V.
10	3IN+	input	Non-inverting (positive) input of op-amp channel 3. Common-mode input range 0 to Vcc-2 V.
11	GND	power_in	Ground / negative supply reference for the device. All voltage values (except differential voltages) are with respect to this network GND.
12	4IN+	input	Non-inverting (positive) input of op-amp channel 4. Common-mode input range 0 to Vcc-2 V.
13	4IN-	input	Inverting (negative) input of op-amp channel 4. Common-mode input range 0 to Vcc-2 V.
14	4OUT	output	Output of op-amp channel 4. High-level output voltage typically Vcc-1.5V (RL=2kΩ); low-level typically 5 mV (RL≤10kΩ).

CAD (KiCad official)

3D model: SOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm2902dr.step`	195 KB	You want the bare part, or you mark your own boards.
`lm2902dr-etched.step`	2.2 MB	You want the part with `LM2902DR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 534 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.
