The analog input diagnostic channels are showing an unexpected result for AD7616-P, what should I do?
The diagnostic channels are used to check the health of the ADC and as a “sanity” check to compare other results against. If the result is unexpected, first check the throughput rate of the ADC. The diagnostic channels are only accurate for throughputs of <250 kSPS. If throughput is ruled out as a problem then a full reset should be performed before checking any system level sources of error.
