GENERAL DESCRIPTION AD8220ARMZ

The AD8220-EP is the first single-supply, JFET input instrumentation

amplifier available in an MSOP package. Designed to meet

the needs of high performance, portable instrumentation, the

AD8220-EP has a minimum common-mode rejection ratio

(CMRR) of 77 dB at dc and a minimum CMRR of 72 dB at 5 kHz

for G = 1. Maximum input bias current at 25°C is 25 pA and

remains below 100 nA over the entire extended industrial

temperature range. Despite the JFET inputs, the AD8220-EP

typically has a noise corner of only 10 Hz.
