LM833DRG from HANSCHIP semiconductor, in a SOP-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 output stage with no deadband crossover distortion; drives loads down to 2.0 kΩ with ±13.7 V typical swing on ±15 V supplies.
2	IN1-	input	Inverting input of op-amp channel 1. High-impedance BJT input; typical input bias current 300 nA, input offset current 10 nA. Must remain within the common-mode input voltage range (-12 V to +14 V typical on ±15 V supplies).
3	IN1+	input	Non-inverting input of op-amp channel 1. High-impedance BJT input; typical input bias current 300 nA. Input voltage must not exceed the magnitude of VCC or VEE.
4	VCC-	power_in	Negative supply rail (VEE). Typically -15 V for specified performance; total supply voltage (VCC to VEE) must not exceed 36 V absolute maximum.
5	IN2+	input	Non-inverting input of op-amp channel 2. High-impedance BJT input; typical input bias current 300 nA.
6	IN2-	input	Inverting input of op-amp channel 2. High-impedance BJT input; typical input bias current 300 nA, input offset current 10 nA.
7	OUT2	output	Output of op-amp channel 2. Low-impedance output stage; drives loads down to 2.0 kΩ with ±13.7 V typical swing on ±15 V supplies. Output short-circuit duration is indefinite.
8	VCC+	power_in	Positive supply rail (VCC). Typically +15 V for specified performance; supply current is 4.0 mA typical (8.0 mA max) for both amplifiers combined.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm833drg.step`	122 KB	You want the bare part, or you mark your own boards.
`lm833drg-etched.step`	2.0 MB	You want the part with `LM833DRG` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 495 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.
