Texas Instruments Analog To Digital Converters (ADC), VQFN-16-EP(3.5x3.5). Pinout cross-checked by two models against the datasheet, KiCad symbol/footprint/3D.
Dedupe duplicate pad names (KiCad same-net multi-pads, pre-2.10 adom-lbr): Fusion refuses the entire library over them; renamed to the name@N convention with connects extended so every pad keeps its pin
Dedupe thermal pad names (six pads named 17 -> 17, [email protected]@6): Fusion's EAGLE importer rejects the whole library on duplicate pad names ('has errors and cannot be opened'); verified opening + full library mint on a real box tonight
