Hi Team,

If AVDD falls to the less than 4.75V in the operation, does SPI communication error occur?

(For example, read values by SPI are incorrect value etc.)

We would like to know your opinion or estimation.

Hi Hide,

This ADC was characterized at specified AVDD range 4.75V to 5.25V, 5V is recommended for AVDD. We did not do the test you mentioned, also we can not guarantee the operation beyond this range.

Thanks&regards,

Dale
