I am trying to use adc101c021 at my board.
on the datasheet, pin id 1 is Va and this pin showed as voltage in.
pin id 3 is Vin and this pin showed as analog in put.
however when I connect power supply (3.3 volt) to the Va, the ic doesnt respond my i2c communication but when I connect to power supply to Vin pin, the ic starts to respond my i2c communication. But this time I can only set configuration pointer and read from only configuration pointer. The other pointer addresses doesnt return default values.
This is really strange situation.
