Hello support team,
This thread is one that is related to the AA.
I've created a new discussion for the following questions.
Please advice the these questions.
When I power down the VCM pin by Register 0x102;
1. We don't need continue to decouple-to-ground with a 0.1uF capacitor. Is this correct?
2. 1.1V is connected to the VCM pin now. Does this cause that cause problems?
We have designed a circuit to enter the common-mode voltage to the VCM pin already.
Therefore, we would like to know whether this circuit must be changed.
3. It is written with Common-mode Range = 0.5V - 1.3V in the data sheet.
When common-mode voltage is 1.1V, we enter analog input signal with an amplitude of 0.6V-1.6V. Does this
reduce the performance of the ADC? (because it is not within the common mode range)
Or, does this meet the specs?
