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 tCONV

internal 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.
