CAD (KiCad official)

  • Symbol: CS1668
  • Footprint: Package_SO:SOP-24_7.5x15.4mm_P1.27mm
  • 3D model: SOP-24, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 2.65 mm nominal SOIC height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: cs1668-etched.step / cs1668-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cs1668.step / cs1668.glb are the bare package body.
