The AD8220 is a single-supply, JFET input instrumentation amplifier available in an MSOP package. It features a rail-to-rail output stage, allowing it to operate on a single +5 V supply or dual supplies up to ±18 V. The device is designed for high-performance portable instrumentation, offering low input bias currents (10 pA maximum for B grade) and high common-mode rejection ratio (CMRR).
