Overview
The AD8508ARUZ-REEL is a quad operational amplifier produced by Analog Devices Inc. This device is part of the AD8505/AD8506/AD8508 family, known for their low power consumption, rail-to-rail input/output capabilities, and zero input crossover distortion. The AD8508ARUZ-REEL is particularly suited for battery-powered applications due to its very low supply current of 20 µA per amplifier and its ability to operate from a single 1.8 V to 5 V power supply or from dual ±0.9 V to ±2.5 V power supplies.
