## CAD (KiCad official)

- Symbol: `ADS114S08BIPBSR`
- Footprint: `Package_QFP:TQFP-32_5x5mm_P0.5mm`
- 3D model: TQFP-32(5x5), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.1 mm nominal TQFP 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: `ads114s08bipbsr-etched.step` / `ads114s08bipbsr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ads114s08bipbsr.step` / `ads114s08bipbsr.glb` are the bare package body.
