Part Information Review and Validation

Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

Review complete: the part mostly matches the datasheet, including MPN/manufacturer and DIP-16 footprint, but pin 8 is mislabeled as NC and should be -VCC, and all terminals currently have Pin Type = Unspecified. The datasheet URL was already set, so I did not update it. Full results are in the TDA1085C Part Information Review project file.
