Hello
The following picture is the circuit diagram.
I want to ask a question that:
Why the reference voltage outputted by my AD7689ACPZ always be 4.5V (4.096V) or 3V (2.5V). I have checked the timing sequence and others as well as researching the datasheet of AD7689ACPZ,there are no problems.
Please help me have a look and give me some advice!
Thanks very very much !
