LM2904AVQDR from Texas Instruments, in a SOIC-8. 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 channel 1. Class-AB output stage capable of sinking/sourcing loads to V- (ground in single-supply operation). Short-circuit to V- allowed indefinitely for VS ≤ 15 V at TA = 25 °C.
2	IN1-	input	Inverting (negative) input of op-amp channel 1. High-impedance BJT input; differential input voltage rated ±32 V (VID). Input voltage range -0.3 V to 32 V.
3	IN1+	input	Non-inverting (positive) input of op-amp channel 1. Common-mode input range includes V- (ground), enabling ground sensing in single-supply operation.
4	V-	power_in	Negative (lowest) supply rail, or ground for single-supply operation. Supply span (V+) - (V-) rated up to 32 V for the AV/A variants (26 V absolute max on plain LM2904).
5	IN2+	input	Non-inverting (positive) input of op-amp channel 2. Common-mode input range includes V- (ground).
6	IN2-	input	Inverting (negative) input of op-amp channel 2. High-impedance BJT input; differential input voltage rated ±32 V.
7	OUT2	output	Output of op-amp channel 2. Class-AB output stage capable of sinking/sourcing loads to V- (ground in single-supply operation).
8	V+	power_in	Positive (highest) supply rail. Recommended supply range 3 V to 32 V (LM2904AV); absolute-maximum total supply is 32 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm2904avqdr.step`	122 KB	You want the bare part, or you mark your own boards.
`lm2904avqdr-etched.step`	2.1 MB	You want the part with `LM2904AVQDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 532 faces against 147 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.
