GENERAL DESCRIPTION
The ADM1067 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 ADM1067 integrates six 8-bit voltage
output DACs. These circuits can be used to implement an open-
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.
