CAD (KiCad official)

  • Symbol: AD9743BCPZ
  • Footprint: Package_DFN_QFN:QFN-72-1EP_10x10mm_P0.5mm_EP6x6mm
  • 3D model: LFCSP-72(10x10), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal QFN 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: ad9743bcpz-etched.step / ad9743bcpz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ad9743bcpz.step / ad9743bcpz.glb are the bare package body.
