THAT1646 Part Audit

flux

I found the footprint asset for silicon-yard/that1646w16-u, but the project index does not expose the internal KiCad .kicad_mod geometry text for pads/lines, so I cannot truthfully extract every exact coordinate, pad size, mask/paste expansion, or outline segment from the indexed data.
What the project data does contain:
Footprint / model assets
  • Footprint asset: SOIC127P1031X264-16N.kicad_mod
  • 3D model asset: THAT1646W16-U.stp
  • Symbol thumbnail asset: THAT1646W16-U Symbol.svg
The PCB footprint node references:
  • asset: SOIC127P1031X264-16N.kicad_mod
The model node references:
  • asset: THAT1646W16-U.stp
Pads present in the indexed footprint
The indexed PCB data lists these 16 pad objects:

plus one additional numbered terminal implied by the 16-pin package, but not returned in the component search results I retrieved
The component index returned explicit pin-number properties for these terminals:
  • NC_1: pin 1
  • NC_2: pin 2
  • OUT-: pin 3
  • SNS-: pin 4
  • GND: pin 5
  • IN: pin 6
  • VEE: pin 7

  • VCC: pin 12
  • SNS+: pin 13
  • OUT+: pin 14
  • NC_7: pin 15
  • NC_8: pin 16
Geometry that can be inferred only from the footprint filename
The filename SOIC127P1031X264-16N.kicad_mod indicates a 16-pin SOIC-style footprint with:
  • Nominal pitch: 1.27 mm
  • Package/lead-span code: 1031, likely 10.31 mm
  • Height/thickness code: 264, likely 2.64 mm
  • Pin count: 16
However, the exact indexed data does not provide:
  • Pad center coordinates
  • Pad width/height
  • Pad shape
  • Pad layers
  • Paste/mask settings
  • Courtyard, fab, or silkscreen line coordinates
  • Pin-Project1/part-level metadata marker found for geometry the part- project :

Audit complete against THAT Corporation datasheet 600078 Rev. 07.
  • Correct: MPN, manufacturer, description, 16-pin count, SO16W package, complete pin numbering/functions, footprint pitch and overall package geometry.
  • Mismatches: IC metadata is incorrectly classified as Logic / AND; every symbol pin type is Unspecified, and pin descriptions are missing.
  • Footprint: Plausible IPC-style SO16W land pattern with 1.27 mm pitch, correct pin-1 marking, paste/mask, and 3D model. The datasheet provides a package outline but no recommended land pattern, so pad sizing cannot be manufacturer-validated.
  • Key specs: ±4 V to ±18 V supplies, +6 dB nominal balanced gain, −101 dBu noise, 0.0007% THD+N, 15 V/µs slew rate, 50 Ω output impedance, and continuous short-circuit protection.
  • Datasheet: A URL was already set, so it was left unchanged. The authoritative official PDF is THAT 1606/1646 Datasheet.
