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). |

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.
