Hi,
The SDADC has three possible input modes,
• Differential mode
• Single-ended offset mode
• Single-ended zero-reference mode
Total 9 pair SDADC channels are available in controller(ex. SDADC_AINP and SDADC_AINM)
in our product we have utilized 8 pair SDADC channels using Single-ended offset mode or Single-ended zero-reference mode for metering application and positive input is connected to SDADC_AINP and external GND is connected to SDADC_AINM also attached reference schematic. kindly review the schematic and suggest

I recommend creating an IOC file to verify pin mapping are okay.
