Part Number: ADS131M04EVM

Hi Team,

My customer is facing issue with ADS131M04EVM board, they are unable to get digital output as the PHI Board is failing to power up the ADC . To debug this issue customer requested schematic of PHI board. Kindly provide the schematic of the PHI-EVM-CONTROLLER-A.

Regards, Shinu.

    Hi Shinu,

    The PHI controller card is taking power from the USB port and then providing proper supply voltages to the EVM board, it's possible it can not be powered up when the USB port of your laptop can not support enough current. I have seen such issue (not for M04EVM) when a portable AC adapter was used on a specific model laptop. I would suggest the customer to use a standard AC adapter or use a desktop PC to check again. The PHI card is a proprietary design and the schematics of this board is not allowed to be shared.

    Best regards,

    Dale
