MC33072ADR2G 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	Output 1	output	Output of op-amp channel 1. Class-AB push-pull NPN output stage with no deadband crossover distortion, capable of driving up to 10,000 pF capacitive loads. Short-circuit current ~30 mA source/sink.
2	Input 1-	input	Inverting input of op-amp channel 1. High-impedance Darlington input; input bias current typ 100 nA (500 nA max). Differential input resistance ~150 MΩ.
3	Input 1+	input	Non-inverting input of op-amp channel 1. Common-mode range extends from VEE to (VCC − 1.8 V), allowing single-supply operation with ground-sensing inputs.
4	VEE	power_in	Negative supply rail (or GND for single-supply operation). Total supply voltage VS = VCC − VEE up to +44 V. In single-supply mode connect to GND; in split-supply mode connect to negative rail (
5	Input 2+	input	Non-inverting input of op-amp channel 2. Common-mode range extends from VEE to (VCC − 1.8 V).
6	Input 2-	input	Inverting input of op-amp channel 2. High-impedance Darlington input, IB typ 100 nA.
7	Output 2	output	Output of op-amp channel 2. Class-AB push-pull NPN output stage with short-circuit protection (~30 mA source/sink).
8	VCC	power_in	Positive supply rail. Operating range 3.0 V to 44 V (single-supply) or up to ±22 V split. Supply current ~1.9 mA/amplifier at ±15 V (2.5 mA max).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc33072adr2g.step`	122 KB	You want the bare part, or you mark your own boards.
`mc33072adr2g-etched.step`	2.6 MB	You want the part with `MC33072ADR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 638 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.
