The AD8665ARJZ is a single-channel, low noise, rail-to-rail, CMOS operational amplifier designed by Analog Devices, offering a blend of low cost and high performance for a wide array of applications. Operating from a single power supply ranging from 4.5V to 16V, or dual supplies of ±2.25V to ±8V, this amplifier is capable of delivering high performance with minimal power consumption. The AD8665ARJZ is particularly suited for battery-powered devices, thanks to its low power draw and the ability to operate at low voltages. Its rail-to-rail input and output feature maximize the dynamic range in applications such as sensor interfacing, portable medical devices, and audio processing. The compact RJZ SOT-23 package makes it an excellent choice for designs where space is at a premium.
