ADM1066 is a super sequencer with margining control and auxiliary ADC inputs. It provides a complete supervisory and sequencing solution for up to 10 supplies.
The ADM1066 Super Sequencer is a configurable supervisory and sequencing device that monitors up to ten supplies, integrates a 12‑bit ADC, six 8‑bit DACs, and a programmable sequencing engine. It supports margining control, fault detection, and SMBus communication, allowing both closed‑loop and open‑loop supply adjustment.
The manual includes functional block diagrams, detailed pin descriptions, electrical specifications, programming guidelines, and ordering information for the 40‑lead LFCSP and 48‑lead TQFP packages. It also covers absolute maximum ratings, thermal resistance, and ESD precautions to ensure reliable operation in multivoltage system applications.
