MC33078DR2G

onsemi · Operational Amplifier · SOIC-8

MC33078DR2G 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. Class-AB bipolar output stage capable of ±14.1 V swing into 10 kΩ, source ~+29 mA / sink ~-37 mA short-circuit current at ±15 V supplies.
2 IN1- input Inverting input of amplifier 1. Typical input bias current 300 nA, input offset current 25 nA, differential input resistance 175 kΩ. ESD-protected via input diodes.
3 IN1+ input Non-inverting input of amplifier 1. Common-mode input voltage range typ ±14 V with ±15 V supplies. ESD-protected via input diodes.
4 VEE power_in Negative supply rail. Operating range from -5 V to -18 V for dual-supply operation; total VCC-to-VEE must not exceed 36 V. Typical quiescent supply current 4.1 mA.
5 IN2+ input Non-inverting input of amplifier 2. Common-mode input voltage range typ ±14 V with ±15 V supplies. ESD-protected via input diodes.
6 IN2- input Inverting input of amplifier 2. Typical input bias current 300 nA, input offset current 25 nA, differential input resistance 175 kΩ. ESD-protected via input diodes.
7 OUT2 output Output of amplifier 2. Class-AB bipolar output stage capable of ±14.1 V swing into 10 kΩ, source ~+29 mA / sink ~-37 mA short-circuit current at ±15 V supplies.
8 VCC power_in Positive supply rail. Operating range from +5 V to +18 V for dual-supply operation; total VCC-to-VEE must not exceed 36 V. Typical quiescent supply current 4.1 mA.

CAD (KiCad official)

  • Symbol: MC33078DR2G
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: mc33078dr2g-etched.step / mc33078dr2g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc33078dr2g.step / mc33078dr2g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mc33078dr2g.step 122 KB You want the bare part, or you mark your own boards.
mc33078dr2g-etched.step 2.7 MB You want the part with MC33078DR2G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 636 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: onsemi datasheet (14 pp, sha256 cbd703eb960e30c5, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
