ADC (LTC2208) property mismatch between schematic and board

[ringof]

Problem

The ADC component (U8, LTC2208) has inconsistent properties between the schematic/library and the board footprint.

Specific mismatches

Property	Library + Schematic	Board Footprint
LCSC Part #	C7458386	C679544
Value	LTC2208CUP#PBF	LTC2208CUP_PBF (underscore vs hash)

Impact

• The LCSC Part # mismatch means the JLCPCB BOM export could reference the wrong part for assembly
• The Value mismatch is cosmetic but indicates the board footprint properties were not synced with the schematic

Recommendation

1. Determine which LCSC Part # is correct (C7458386 or C679544) — verify on JLCPCB/LCSC that it matches the LTC2208CUP#PBF in the correct package
2. Sync the board footprint properties to match the schematic: Update from Schematic in KiCad or manually fix the board properties
3. Run ERC and DRC after the fix
4. Regenerate the BOM to confirm the correct LCSC # propagates

Location

• Library: TAPRX-888 KiCad/Library.kicad_sym → LTC2208CUP_PBF (LCSC: C7458386)
• Schematic: TAPRX-888 KiCad/TAPRX-888.kicad_sch → U8 instance (LCSC: C7458386)
• Board: TAPRX-888 KiCad/TAPRX-888.kicad_pcb → U8 footprint (LCSC: C679544)
