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

MIC3003 is sampled in sequence. All five parameters are

sampled and the results updated within the tCONV duration

given in the “Electrical Characteristics” section. In OEM

mode, the channel that is normally used to measure VIN

may be assigned to measure the level of the VDDA pin or

one of five other nodes. This provides a kind of analog

loopback for debug and test purposes. The VAUX bits in

OEMCFG0 control which voltage source is being

sampled. The various VAUX channels are level-shifted

differently depending on the signal source, resulting in

different LSB values and signal ranges. See Table 5.
