XTR101APG4 | Texas Instruments

Precision, low drift, XTR101APG4, Texas Instruments

The XTR101APG4 is a microcircuit 4-20 mA, two-wire transmitter containing a high accuracy instrumentation amplifier (IA), a voltage-controlled output current source, and dual-matched precision current reference. This combination 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.
