mc33079dr2g.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 14 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

MC33079DR2G

onsemi · Operational Amplifier · SOIC-14

MC33079DR2G from onsemi, in a SOIC-14. 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 op-amp channel 1. Low-impedance push-pull output; typical short-circuit current ±30 mA.
2 IN1- input Inverting input of op-amp channel 1. High-impedance bipolar input; typical input bias current 300 nA.
3 IN1+ input Non-inverting input of op-amp channel 1. High-impedance bipolar input; common-mode range extends to within ~1.8 V of each supply rail.
4 VCC power_in Positive supply rail. Operating range ±2.5 V to ±18 V (5 V to 36 V single-supply). Typical quiescent current 4 mA per amplifier.
5 IN2+ input Non-inverting input of op-amp channel 2. High-impedance bipolar input.
6 IN2- input Inverting input of op-amp channel 2. High-impedance bipolar input.
7 OUT2 output Output of op-amp channel 2. Low-impedance push-pull output.
8 OUT3 output Output of op-amp channel 3. Low-impedance push-pull output.
9 IN3- input Inverting input of op-amp channel 3. High-impedance bipolar input.
10 IN3+ input Non-inverting input of op-amp channel 3. High-impedance bipolar input.
11 VEE power_in Negative supply rail (or GND in single-supply operation). Operating range ±2.5 V to ±18 V split, or 0 V for single-supply 5 V to 36 V use.
12 IN4+ input Non-inverting input of op-amp channel 4. High-impedance bipolar input.
13 IN4- input Inverting input of op-amp channel 4. High-impedance bipolar input.
14 OUT4 output Output of op-amp channel 4. Low-impedance push-pull output.

CAD (KiCad official)

  • Symbol: MC33079DR2G
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: mc33079dr2g-etched.step / mc33079dr2g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc33079dr2g.step / mc33079dr2g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mc33079dr2g.step 195 KB You want the bare part, or you mark your own boards.
mc33079dr2g-etched.step 2.9 MB You want the part with MC33079DR2G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 699 faces against 237 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.
