GENERAL DESCRIPTION
The ADM1063 is a configurable supervisory/sequencing device
that offers a single-chip solution for supply monitoring and
sequencing in multiple supply systems. In addition to these
functions, the ADM1063 integrates a 12-bit ADC and six 8-bit
voltage output DACs. These circuits can be used to implement a
closed-loop margining system, which enables supply adjustment
by altering either the feedback node or reference of a dc-to-dc
converter using the DAC outputs.
