The Analog Devices AD8609ARZ-REEL7 is a quad precision CMOS rail-rail operational amplifier. It is a low power, 4-channel monolithic amplifier designed to provide precision performance and low power dissipation at high accuracy, and is optimized for applications where supply voltages are limited. The model features rail to rail input and output operation for all channels, a low supply current requirement of 1.4mA maximum per amplifier, a low input offset voltage of 50µV maximum, and a high output drive current of 10mA. The amplifier has a bandwidth of 9MHz, a low noise of 3nV/vHz, and an input bias current of 10pA typical. Furthermore, the AD8609ARZ-REEL7 features a unity gain stability and a wide operating temperature range of -40°C to +125°C.
