Product Overview

The XTR105PA is a 2-wire Current Transmitter with sensor excitation and linearization. It provides complete current excitation for platinum RTD temperature sensors and bridges, instrumentation amplifiers and current output circuitry on a single integrated circuit. Versatile linearization circuitry provides a 2nd-order correction to the RTD, typically achieving a 40:1 improvement in linearity. Instrumentation amplifier gain can be configured for a wide range of temperature or pressure measurements. Total unadjusted error of the complete current transmitter is low enough to permit use without adjustment in many applications. This includes zero output current drift, span drift and nonlinearity. The XTR105 operates on loop power-supply voltages down to 7.5V.
  • Low unadjusted error
  • Two precision current sources (800µA each)
  • Linearization
  • 2-wire RTD operation
  • Low offset drift (0.4µV/°C)
  • Low output current noise (30NAPP)
  • High PSR (110dB minimum)
  • High CMR (86dB minimum)
  • Green product and no Sb/Br
IC can be damaged by ESD. We recommend that all ICs be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
