XTR101_高精度、低漂移4-20mA两线制发

推荐备选器件
  • XTR117 - ?General purpose 2-wire 4 to 20mA transmitter. 7.5V to 40V supply. 5V v-reg on board.
  • XTR108 - ?More programmability than XTR101. 7.5V to 24V supply. 2 matched 500uA current sources instead of 1mA sources.
  • XTR105 - ?Includes linearization circuitry. 7.5V to 36V supply. 2 matched 800uA current sources instead of 1mA sources.
  • XTR112 - ?Includes linearization circuitry. 7.5V to 36V supply. 2 matched 250uA current sources instead of 1mA sources.

XTR101

The XTR101 is a microcircuit, 4-20mA, 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-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. It can be used by OEMs producing transmitter modules or by data acquisition system manufacturers.
