ADS7863A: Schematic review

Part Number: ADS7863A

Hi Team,

This is FAE Jayden, my customer is using ADS7863A in their design, could you help check the schematics? Thanks.

  • The single-end ADC is used in their design, could you help check?
  • I found the thermal pad is directly connected to AGND and BGND by vias in datasheet? Aren't AGND and BGND short-circuited through the thermal pad? Then wouldn’t the high-frequency isolation between AGND and BGND have no effect? Should the thermal pad only be connected to AGND or BGND?

Thanks

Brs

Jayden
