MC33072DR2G 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	Op-amp A output. All-NPN class-AB stage; drives up to 10,000 pF load with typical VOH ~14 V and VOL ~-14.7 V on +/-15 V supplies. Short-circuit current typically 30 mA (source/sink).
2	Input 1-	input	Op-amp A inverting input. Darlington bipolar input stage with typical input bias current 100 nA and 150 MOhm differential input resistance. Common-mode range VEE to (VCC-1.8 V).
3	Input 1+	input	Op-amp A non-inverting input. Common-mode input range includes ground (VEE), enabling single-supply operation. Typical differential input capacitance 2.5 pF.
4	VEE	power_in	Negative supply / ground. For single-supply operation tie to GND; for split-supply use down to -22 V. Total VCC-to-VEE supply must not exceed 44 V. Typical supply current 1.9 mA per amplifier at +/-15 V.
5	Input 2+	input	Op-amp B non-inverting input. Common-mode input range includes ground (VEE). Typical differential input capacitance 2.5 pF.
6	Input 2-	input	Op-amp B inverting input. Darlington bipolar input stage with typical input bias current 100 nA and 150 MOhm differential input resistance.
7	Output 2	output	Op-amp B output. All-NPN class-AB stage; drives up to 10,000 pF load with typical VOH ~14 V and VOL ~-14.7 V on +/-15 V supplies. Short-circuit current typically 30 mA (source/sink).
8	VCC	power_in	Positive supply. Single-supply range 3.0 V to 44 V, or split-supply up to +22 V (with

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc33072dr2g.step`	122 KB	You want the bare part, or you mark your own boards.
`mc33072dr2g-etched.step`	2.5 MB	You want the part with `MC33072DR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 612 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.
