GENERAL DESCRIPTION

The ADM1069 Super Sequencer® 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 ADM1069 integrates a 12-bit ADC and

four 8-bit voltage output DACs. These circuits can be used to

implement a closed-loop margining system that enables supply

adjustment by altering either the feedback node or reference of

a dc-to-dc converter using the DAC outputs.
