AD8422ARMZ

AD8422 is a high performance, low power, rail-to-rail precision instrumentation amplifier. It processes signals with ultralow distortion performance that is load independent over its full output range. It employs new process technologies and design techniques to achieve higher dynamic range and lower errors than its predecessors, while consuming less than one-third of the power. It uses robust input protection that ensures reliability without sacrificing noise performance. It error free with high source impedance, allowing multiple sensors to be multiplexed to the inputs. This amplifier is widely used in application such as medical instrumentation, industrial process controls, strain gauges, transducer interfaces, precision data acquisition systems, channel-isolated systems, portable instrumentation etc.
