CAD (KiCad official)

  • Symbol: OPA227UA
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: opa227ua-etched.step / opa227ua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa227ua.step / opa227ua.glb are the bare package body.

Provenance

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