Hot-selling and scarce ADM1062ACPZ Super Sequencer with Margining Control and Temperature Monitoring QFN40 spot stock

Product Descriptions

The ADM1062 Super Sequencer® is a configurable supervisory/sequencing device that offers a single-chip solution for supplymonitoring and sequencing in multiple-supply systems .In additionto these functions,the ADM1062 integrates a 12-bit ADC and six8-bit voltage output DACs.These circuits can be used to implementa closed-loop margining system that enables supply adjustmentby altering either the feedback node or the reference of a dc-to-dcconverter using the DAC outputs .​
