Hi,
I have a question regarding to the ADS4245 digital inputs : CTRL[1:3],SCLK,SEN,RESET-
Naturally, since they defined has digital pins- – I would connect them to the digital reference rail - DRVDD.
But in the EVB these pins referenced to AVDD , and the datasheet states:
SEN: " This pin has an internal 150-kΩ pullup resistor to AVDD"
RESET: " To put the device into parallel configuration mode, keep RESET tied high (AVDD)"
Can you please confirm that TI's recommendation is to connect these pins (via PU/Voltage divider, when required) to AVDD?
Can you confirm that this is a mistake (2AVDD instead of AVDD) in the datasheet:
BR,
Rotem
