Hello Team,
The ADC has several calibration modes. One important calibration procedure seems to be the offset calibration. The internal occurring DC-offsets (in dual channel mode) should be eliminated with this calibration procedure, am I right?
Can you provide a detailed description on how to use this calibration procedure during the ADC initialization.
The ADC datasheet describes, that there should be no Signal near or at DC. In our device, we can not be sure, that there is no DC-signal at the input of the RX-path.
- Is it really necessary to disable the input signal during the offset calibration?
- Do we have to disable the input signal during the other calibration procedures, too?
- Is it possible to disable the input signals in the ADC?
Thanks and Best Regards,
Hans
