GENERAL DESCRIPTION  
The ADM1066 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 ADM1066 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/dc  
converter using the DAC outputs.  
User EEPROM: 256 bytes  
Industry-standard 2-wire bus interface (SMBus)  
Guaranteed PDO low with VH, VPn = 1.2 V

40-lead 6 mm × 6 mm LFCSP and  
48-lead 7 mm × 7 mm TQFP packages
