SymbolFootprint3D modelPinsfor all variants
  • ✓Datasheet: the page already carries TI's current edition (SLYS022A, June 2020, revised June 2021; sha256 72bbe6e1bf379bb3 matches ti.com/lit/ds/symlink/ina228-q1.pdf fetched 2026-10-27); edition now recorded
  • ✓All 10 pins match Table 5-1 and Figure 5-1 (DGS 10-pin VSSOP, p.3) by number and name (A1, A0, ALERT, SDA, SCL, VS, GND, VBUS, IN-, IN+; the datasheet prints IN– with a typographic dash, ALERT has no overbar); no renames needed
  • ✓Pin types agree with Table 5-1: A0/A1/SCL digital inputs, SDA digital input/output (bidirectional), ALERT open-drain digital output, VBUS/IN+/IN- analog inputs, VS power supply, GND ground
  • ✓All 10 descriptions rewritten to Table 5-1 wording (p.3); the earlier text added facts not in the pin table (2.94 MHz, 16 addresses, 1 MΩ, decoupling advice)
  • ✓Orderable INA228AQDGSRQ1 is VSSOP (DGS), 10 pins, 2500 large T&R, marking 228Q (Package Option Addendum, p.43)
  • ✓Footprint vs DGS0010A (p.47-48): the open item asked to confirm the KiCad TSSOP-10_3x3mm_P0.5mm land against DGS; it has 10 pads 1.45 x 0.30 mm at e = 0.50 mm, as TI's land pattern example (10X 1.45 x 0.3, 8X 0.5); pad centres 4.30 mm apart vs TI's (4.4) reference, both cover the lead (E 4.75-5.05, L 0.4-0.7); pad width 0.30 over b 0.17-0.27; no exposed pad; pin 1 top-left, pins 1-5 down the left side as Figure 5-1
  • ✓3D body 4.90 x 3.00 x 1.10 mm against E 4.75-5.05 (lead span), D 2.9-3.1, A 1.1 max (p.47); seated on z = 0, centred on the pads
  • ✓DigiKey 296-INA228AQDGSRQ1TR-ND (tape and reel; DigiKey product URL names INA228AQDGSRQ1) and Mouser 595-INA228AQDGSRQ1 kept and added to specs
  • ✓Symbol and footprint Datasheet properties point at the manufacturer datasheet URL
  • ✓Symbol Datasheet / MPN / Manufacturer / DigiKey / Mouser / LCSC properties agree with page.json; footprint Datasheet property points at the manufacturer datasheet URL
  • ✓component-page-verify: all checks pass

reviewfor all variants
  • •Footprint is KiCad Package_SO:TSSOP-10_3x3mm_P0.5mm while the datasheet package is DGS (VSSOP-10) and the KiCad INA228 symbol filters for VSSOP-10; confirm the land pattern against the DGS package drawing.
16 Oct 2026Claude (AI build)Automated build checks (awaiting human validation)superseded
SymbolFootprint3D modelPinsfor all variants
  • ✓Footprint extracted pad-for-pad from the source board and normalized to the footprint frame (back-side parts un-mirrored)
  • ✓3D model seated z=0 at footprint origin (placement inverse; method centroid-matched to KiCad library models on 59 cases)
  • ✓adom-lbr generate + lint passed
  • ✓10 of 10 pins described from the datasheet (adom-ds2sf, page-cited)
  • •Not yet checked by a person: land pattern vs datasheet, pin-1/orientation, 3D body vs drawing
