Overview
The AD8618ARUZ from Analog Devices Inc. is a quad-channel, rail-to-rail, input and output, single-supply operational amplifier. It is distinguished by its very low offset voltage, wide signal bandwidth, and low input voltage and current noise. The AD8618 uses a patented trimming technique to achieve superior precision without the need for laser trimming. This amplifier is fully specified to operate from 2.7 V to 5 V single supplies, making it versatile for various applications.
