UTC Unisonic Tech · Operational Amplifier · SOP-8

MC34072G-S08-R from UTC Unisonic Tech, 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 Amplifier 1 output. Push-pull all-NPN output stage; typical swing -14.7V to +14V with ±15V supplies. Short-circuit protected (I_SC ~30mA).
2 IN1- input Amplifier 1 inverting input. Darlington input stage; typical differential input resistance 150MΩ, input bias current 100nA typ (500nA max).
3 IN1+ input Amplifier 1 non-inverting input. Common-mode input range includes V_EE (ground); extends from V_EE to (V_CC - 1.8V) at 25°C.
4 VEE power_in Negative supply / ground pin. Connect to ground for single-supply operation or to the negative rail for split-supply operation. Total supply (V_CC to V_EE) 3.0V to 44V (±22V max).
5 IN2+ input Amplifier 2 non-inverting input. Same characteristics as amplifier 1: Darlington input stage, common-mode range includes V_EE.
6 IN2- input Amplifier 2 inverting input. Input bias current 100nA typ (500nA max), input offset current 6nA typ (50nA max).
7 OUT2 output Amplifier 2 output. Push-pull all-NPN output stage with output short-circuit protection; drives large capacitive loads (0pF to 10,000pF).
8 VCC power_in Positive supply pin. Range 3.0V to 44V single-supply (or up to +22V split-supply relative to V_EE). Supply current ~1.9mA typ per amplifier at ±15V, no load.

Two STEP files. Same geometry, different body top:

File Size Use it when
mc34072g-s08-r.step 122 KB You want the bare part, or you mark your own boards.
mc34072g-s08-r-etched.step 3.0 MB You want the part with MC34072G-S08-R already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 711 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.
