3 IN1+ input Non-inverting input of amplifier 1. Common-mode range from VEE to (VCC - 1.8 V); do not exceed VCC or VEE on either input.
4 VEE power_in Negative supply / ground. Total supply (VCC - VEE) rated up to +36 V. In single-supply operation, tie to ground.
5 IN2+ input Non-inverting input of amplifier 2. Common-mode range from VEE to (VCC - 1.8 V); do not exceed VCC or VEE on either input.
6 IN2- input Inverting input of amplifier 2. Bipolar input with ~300 nA typical input bias current and 16 MΩ differential input resistance.
7 OUT2 output Output of amplifier 2. NPN output stage with symmetrical source/sink capability (±37 mA typ short-circuit current); unity-gain stable with capacitive loads up to 500 pF.
8 VCC power_in Positive supply. +3.0 V to +36 V single-supply, or ±1.5 V to ±18 V split-supply. Quiescent current ~2.15 mA per amplifier.

  • Symbol: MC33272ADR2G
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: mc33272adr2g-etched.step / mc33272adr2g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc33272adr2g.step / mc33272adr2g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mc33272adr2g.step 122 KB You want the bare part, or you mark your own boards.
mc33272adr2g-etched.step 2.6 MB You want the part with MC33272ADR2G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 628 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.
