Overview
The AD8616AR is a dual, rail-to-rail input and output, single-supply operational amplifier produced by Analog Devices Inc. This amplifier is known for its high precision and low noise characteristics, making it suitable for a wide range of applications. It features very low offset voltage, low input bias current, and wide signal bandwidth, which are achieved through Analog Devices' patented DigiTrim® trimming technique. The AD8616AR operates from a single supply of 2.7 V to 5 V and is fully specified over the extended industrial temperature range of -40°C to +125°C.
