MC33078DT

STMicroelectronics · Operational Amplifier · SOIC-8

MC33078DT from STMicroelectronics, 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 Output 1 output Op-amp A output. Class-AB output stage delivering ±14.3 V/-14.6 V swing into 10 kΩ and ~29 mA source / 37 mA sink short-circuit current.
2 Inverting input 1 input Op-amp A inverting input (IN−). Typical bias current 250 nA, input resistance ~175 kΩ, input capacitance ~12 pF.
3 Non-inverting input 1 input Op-amp A non-inverting input (IN+). Input common-mode range ±13 V min (±14 V typ) with ±15 V rails.
4 VCC- power_in Negative supply rail (V−). Shared by both op-amps. Operating range ±2.5 V to ±15 V (or single-supply up to +36 V total across VCC+/VCC−).
5 Non-inverting input 2 input Op-amp B non-inverting input (IN+). Input common-mode range ±13 V min (±14 V typ).
6 Inverting input 2 input Op-amp B inverting input (IN−). Typical bias current 250 nA.
7 Output 2 output Op-amp B output. Class-AB output stage; large output swing and symmetrical source/sink currents.
8 VCC+ power_in Positive supply rail (V+). Shared by both op-amps. Typical supply current 4 mA (5.5 mA max). Absolute max ±18 V (or 36 V single-supply).

CAD (KiCad official)

  • Symbol: MC33078DT
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: mc33078dt-etched.step / mc33078dt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc33078dt.step / mc33078dt.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
mc33078dt.step 122 KB You want the bare part, or you mark your own boards.
mc33078dt-etched.step 2.1 MB You want the part with MC33078DT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 513 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: STMicroelectronics datasheet (15 pp, sha256 51b16bf21965c6dd, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
