Part Review and Datasheet Verification

flux

Reviewed the ADS1293CISQ/NOPB part against the official TI datasheet.
Datasheet: already resolves to TI’s official ADS1293 datasheet; no update was needed.
MPN/package: ADS1293CISQ/NOPB, TI, WQFN/RSG, 28 pins, 5 × 5 mm body, –20°C to 85°C.
Key specs: 3-channel 24-bit ECG AFE, VDD 2.7–5.5 V, VDDIO 1.65–3.6 V or ≤ VDD, up to 25.6 ksps pace / 6.4 ksps ECG, ±400 mV differential input range, 7 µVpp noise over 0.1–40 Hz high-resolution mode.
Cross-check result: pins 1–28 match the datasheet names and numbering. The footprint has 29 pads, which is plausible for 28 leads plus exposed/DAP pad, but the extra pad is currently named GND / pin 29. The datasheet identifies DAP as no-connect, not GND, so this is the main mismatch to fix. Also, all terminal pin types are currently Unspecified; they should be updated to Analog Input/Output/I/O, Digital Input/Output/I/O, Supply, or No Connect per the datasheet.

Update all terminal pin types to match the datasheet pin function table also add section for all the pins based on the datasheet

flux

I’ll update each terminal’s Pin Type and Section from the ADS1293 datasheet pin-function table, then verify the properties on the schematic.

flux

Updated and verified all ADS1293 terminals with datasheet-based Pin Type and Section properties.
Notable update: the extra pad currently named GND / pin 29 was marked No Connect and sectioned as Exposed Pad / DAP, with its pin description set to “DAP; no connect per datasheet.” The tool accepted the datasheet-exact pin type labels, though some are outside Flux’s standard pin-type suggestions.
