Analog-to-Digital Converter/Signal Monitoring
A block diagram of the monitoring circuit is shown below.
Each of the five analog parameters monitored by the
MIC3002 are sampled in sequence. All five parameters
are sampled and the results updated within the t

shifted differently depending on the signal source,
resulting in different LSB values and signal ranges. See
