XTR101AP

The XTR101AP is a 2-wire precision low drift Microcircuit 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-the-art 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 allows even higher precision. The two-wire transmitter allows signal and power to be supplied on a single wire pair by modulating the power-supply current with the input signal source. The transmitter is immune to voltage drops from long runs and noise from motors, relays, actuators, switches, transformers and industrial equipment.
