AD627ARZ-RL

AD627 is an integrated, micropower instrumentation amplifier. It offers superior flexibility by allowing the user to set the gain of the device with a single external resistor while conforming to the 8-lead industry-standard pinout configuration. The device does not compromise performance, unlike other micropower instrumentation amplifiers. Low voltage offset, offset drift, gain error, and gain drift minimize errors in the system. It also minimizes errors over frequency by providing excellent CMRR over frequency. Because the CMRR remains high upto 200Hz, line noise and line harmonics are rejected. It is widely used in application such as 4mA to 20mA loop-powered applications, low power medical instrumentation—ECG, EEG, transducer interfacing, thermocouple amplifiers, industrial process controls, low power data acquisition, portable battery-powered instruments etc.
