Symbol: ADS114S08IPBSR

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: ads114s08ipbsr-etched.step / ads114s08ipbsr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ads114s08ipbsr.step / ads114s08ipbsr.glb are the bare package body.
