MC34072DR2G 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 amplifier 1. All-NPN output stage with symmetrical source/sink, ISC ~30 mA typical, capable of driving 0 pF to 10,000 pF loads without deadband crossover distortion. |
| 2 | IN1- | input | Inverting input of amplifier 1. Darlington PNP input stage with ~150 MOhm differential input resistance and ~2.5 pF input capacitance. Common-mode range extends from VEE to (VCC - 1.8 V). |
| 3 | IN1+ | input | Non-inverting input of amplifier 1. Common-mode voltage range includes ground (VEE), enabling single-supply operation. Input bias current 100 nA typical. |
| 4 | VEE | power_in | Negative supply / ground. Connect to 0 V for single-supply operation or to a negative rail for split supplies. Total (VCC - VEE) must not exceed 44 V. |
| 5 | IN2+ | input | Non-inverting input of amplifier 2. Common-mode voltage range includes ground (VEE). Input bias current 100 nA typical. |
| 6 | IN2- | input | Inverting input of amplifier 2. Darlington PNP input stage, ~150 MOhm differential input resistance. Input differential voltage should not exceed the magnitude of VCC or VEE. |
| 7 | OUT2 | output | Output of amplifier 2. All-NPN output stage; output swing typically 14 V / -14.7 V at ±15 V supplies with a 2 kOhm load. Short-circuit protected indefinitely. |
| 8 | VCC | power_in | Positive supply. 3.0 V to 44 V single-supply, or up to ±22 V split. Supply current ~1.9 mA per amplifier at ±15 V (no load). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 583 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.
