CAD (KiCad official)

  • Symbol: L272D
  • Footprint: Package_SO:SOIC-16_3.9x9.9mm_P1.27mm
  • 3D model: SOIC-16 (KiCad packages3D, STEP)
  • 3D model files: l272d-etched.step / l272d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l272d.step / l272d.glb are the bare package body.

Provenance

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