The AD8574-EP is a zero-drift, single-supply, rail-to-rail I/O quad operational amplifier with high gain, high CMRR, high PSRR, low input bias current, and low supply current.
The document describes the AD8574-EP, a quad operational amplifier featuring ultralow offset voltage (1 µV) and drift. It utilizes a patented spread-spectrum auto-zero technique to eliminate intermodulation effects in AC applications while supporting defense and aerospace standards (AQEC). The device operates from a single supply of 2.7 V to 5 V with rail-to-rail input and output swings.
