General Description

The AD8220 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 has a minimum common-mode rejection ratio (CMRR) of 86 dB at dc and a minimum CMRR of 80 dB at 5 kHz for G = 1.

Maximum input bias current is 10 pA and typically remains below 300 pA over the entire industrial temperature range.
