LM833DR2G from onsemi, 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. Low-impedance analog output capable of driving typical audio loads.
2	IN1-	input	Inverting input of op-amp channel 1. High-impedance analog input.
3	IN1+	input	Non-inverting input of op-amp channel 1. High-impedance analog input.
4	VEE	power_in	Negative supply rail. Typically connected to a negative supply for split-supply operation or to GND for single-supply operation. Supply range ±5 V to ±18 V (total 10 V to 36 V).
5	IN2+	input	Non-inverting input of op-amp channel 2. High-impedance analog input.
6	IN2-	input	Inverting input of op-amp channel 2. High-impedance analog input.
7	OUT2	output	Output of op-amp channel 2. Low-impedance analog output capable of driving typical audio loads.
8	VCC	power_in	Positive supply rail. Supply range ±5 V to ±18 V (total 10 V to 36 V).

CAD (KiCad official)

3D model: SOIC-8 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm833dr2g.step`	122 KB	You want the bare part, or you mark your own boards.
`lm833dr2g-etched.step`	2.2 MB	You want the part with `LM833DR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 540 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.
