Our customer is designing with your AD7762 sigma delta ADC.
So I have a question as following.
Do you have the waiting time as for after release the power down and the diff-amp power down?
After below step-4, durling 540 to 600usec he could not get the correct value.
Checking DValid was correct.
Why we cannot catch the corret value for 540-600usec?
Write 0x0022 to the control register-2
Release the power down and the diff-amp power down
Write 0x000B to the control register-1
Input value : Fixed
Read the ADC data
External power voltage ,and Vref coltage were correct.
