AD8220ARMZ

AD8220 is a single-supply, JFET input instrumentation amplifier. It is designed to meet the needs of high performance, portable instrumentation. With the proliferation of mixed-signal processing, the number of power supplies required in each system has grown. The device is designed to alleviate this problem. Its rail-to-rail output stage maximizes dynamic range on the low voltage supplies common in portable applications. A reference pin allows the user to offset the output voltage. This feature is useful when interfacing with analogue-to-digital converters. It is widely used in application such as medical instrumentation, precision data acquisition, transducer interfaces etc.
