The AD8220ARMZ is a JFET input Instrumentation Amplifier with Rail-to-Rail output in MSOP package. Designed to meet the needs of high performance, portable instrumentation, this has a minimum common-mode rejection ratio (CMRR) of 86dB at DC and a minimum CMRR of 80dB at 5kHz for G=1. Maximum input bias current is 10pA and typically remains below 300pA over the entire industrial temperature range. With the proliferation of mixed-signal processing, the number of power supplies required in each system has grown. Its rail-to-rail output stage maximizes dynamic range on the low voltage supplies common in portable applications. Its ability to run on a single 5V supply eliminates the need to use higher voltage, dual supplies. This draws a maximum of 750μA of quiescent current, making it ideal for battery powered devices.
