Analog Devices AD8224 Precision Dual-Channel JFET Input Rail-to-Rail Instrumentation Amplifier Datasheet
The document describes the AD8224, the first single-supply, JFET input instrumentation amplifier available in a space-saving 16-lead LFCSP package. It is designed for high-performance portable instrumentation, offering double channel density with lower cost per channel compared to typical single instrumentation amplifiers.
Key features include rail-to-rail output capability, operation on a single +5 V supply or dual supplies up to ±18 V, and low input bias currents of 10 pA maximum (B Grade). The device supports gain settings from 1 to 1000 with a single resistor.
