Overview
The AD8541ART-R2, produced by Analog Devices Inc., is a single rail-to-rail input and output, single-supply operational amplifier. This component is part of the AD8541/AD8542/AD8544 family, which includes single, dual, and quad configurations. The AD8541ART-R2 is designed for low power consumption and high performance, making it suitable for a wide range of applications. It operates on a single supply voltage from 2.7 V to 5.5 V and features a very low supply current of 45 µA per amplifier. This amplifier is optimized for use in battery-operated devices and other low-power systems due to its low current consumption and high bandwidth of 1 MHz.
