ADM1067 is a super sequencer product from Analog Devices. It features 10-supply supervisory and sequencing functions, and supports 14.4V VH and 6V VPx inputs. Output voltage can reach 1.375V.
The ADM1067 Super Sequencer is a configurable supervisory and sequencing device that supports up to ten supply fault detectors and ten programmable driver outputs. It integrates six 8‑bit voltage‑output DACs for open‑loop margining, allowing supply voltage adjustment via external de‑to‑de converters.
The document provides functional block diagrams, pin‑out tables, absolute maximum ratings, thermal resistance data, and detailed electrical specifications such as voltage ranges, current consumption, and EEPROM size. It also describes SMBus communication, sequencing engine timing, and recommended external components for stable operation.
