Product Summary

The XTR101AU is a precision, low drift 4-20mA two-wire transmitter. The XTR101AU is a microcircuit, 4-20mA, two-wireb transmitter containing a high accuracy instrumentation amplifier (IA), a voltage-controlled output current source, and dual-matched precision current reference. This combination of the XTR101AU is ideally suited for remote signal conditioning of a wide variety of transducers such as thermocouples, RTDs, thermistors, and strain gauge bridges. State-of-theart design and laser-trimming, wide temperature range operation, and small size make it very suitable for industrial process control applications. In addition, the optional external transistor of the XTR101AU allows even higher precision.
