The Texas Instruments XTR105 is a monolithic 4-20mA, 2-wire current transmitter with two precision current sources. It provides complete current excitation for platinum RTD temperature sensors and bridges, instrumentation amplifiers, and current output circuitry on a single integrated circuit.
LOW UNADJUSTED ERROR TWO PRECISION CURRENT SOURCES: 800 μA each LINEARIZATION 2-OR 3-WIRE RTD OPERATION LOW OFFSET DRIFT: 0.4 μV/°C LOW OUTPUT CURRENT NOISE: 30NAPP HIGH PSR: 110dB minimum HIGH CMR: 86dB minimum WIDE SUPPLY RANGE: 7.5V to 36V DIP-14 AND SO-14 PACKAGES
4mA-to-20mA Current-Loop Communication
Current loop systems are used in electrically noisy industrial environments for sending analogue sensor data over long distances of 300m or more.
