Pin Audit and Grouping


can you group together pins by their functions?
for example for Power, 3v3, gnd_1 gnd_2 etc
NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function.
Yes. I’ll assign each physical pin to exactly one broad functional group based on its primary datasheet function, keep Section equal to Pin Group, and organize power first/top, grounds last/bottom, with the remaining groups split left/right.
Pin grouping and datasheet-based descriptions are now applied. I’m verifying all 33 assignments and completing the metadata/package/footprint audit.
Grouped all 33 pins by their primary function with no duplicates, matching Section = Pin Group, and added datasheet-based pin descriptions. The existing official ADI datasheet URL is correct.
Audit findings
  • Correct: MPN, manufacturer, 33 pads, 32-lead 5 × 5 mm LFCSP plus EPAD, 0.50 mm pitch, and pin-to-pad numbering.
  • Key specs: 16-bit current/voltage DAC, ±33 V rails, 1.71–5.5 V logic, SPI up to 50 MHz, −40°C to +115°C.
  • Mismatches: package property says “TO” but should be LFCSP / CP-32-30; pin 31 is named VDPC instead of datasheet VDPC+; all pin electrical types remain Unspecified; EPAD description should explicitly state connection to AVSS or leave unconnected.
  • Footprint concern: the imported courtyard outline appears included in the silkscreen geometry, and the 3.7 mm exposed-pad paste aperture is not windowed.
