Overview
The AD8659ARZ-RL is a quad micropower, precision, rail-to-rail input/output operational amplifier produced by Analog Devices Inc. This device is optimized for low power consumption and a wide operating supply voltage range, making it suitable for various applications requiring high precision and low power usage.
The AD8659ARZ-RL operates from a single supply of 2.7 V to 18 V or a dual supply of ±1.35 V to ±9 V, with a typical quiescent supply current of 18 μA per amplifier. It features low offset voltage, low input bias current, and high immunity to electromagnetic interference, thanks to Analog Devices' patented DigiTrim® trimming technique.
