My customer is considering ADS8556 and he has following 2 questions. Could you kindly help?
1. From following block diagram, REFC_A, B, C seems connecting with output of a buffer, customer wants to know what voltage level on REFC_A, B, C.
Customer wants to choose voltage rating of capacitor based on it. Since 16V capacitor is smaller than 25V capacitor, they want to use 16V capacitor if it is okay.
2. Does ADS8556 have power sequencing limitation for power supply? Customer is asking this since some ADC from other manufacturer had power sequencing limitation.
