Hello,
I'm using an AD7328 with external 3V reference. When I try to read the temperature register I get values that, while quite near, do not match those shown in the data sheet.
I found no data for the case of external reference, nor any formula to translate between values read and temperature. How can I interpret the readings?
Another problem I have with the chip is that when I set mode 3 (0-10V) in the range registers, the values I read are the same as for mode 1, suggesting that the actual range is 0-5V (6v in my case). What happens? Is the data sheet wrong?
