Overview
The ADA4091-2ARZ is a dual, micropower, single-supply operational amplifier produced by Analog Devices Inc. This amplifier features a 1.2 MHz bandwidth and is designed with rail-to-rail inputs and outputs. It can operate from a single supply voltage ranging from +3V to +30V, as well as from dual supplies ranging from ±1.5V to ±15V. The ADA4091-2ARZ is notable for its unique input stage that provides overvoltage protection (OVP), allowing the input voltage to exceed either supply voltage safely without phase reversal or latch-up.
