Product Summary

The XTR105P is a monolithic 4-20mA, two-wire current transmitter with two precision current sources. It provides complete current excitation for Platinum RTD temperature sensors and bridges, instrumentation amplifier, 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.

Parametrics

XTR105P absolute maximum ratings: (1)Power Supply, V+ (referenced to IO pin): 40V; (2)Storage Temperature Range: -55℃ to +125℃; (3)Lead Temperature (soldering, 10s): +300℃; (4)Junction Temperature: +165℃.

Features

XTR105P features: (1)low unadjusted error; (2)two precision current sources; (3)rtd or bridge excitation; (4)linearization; (5)two or three-wire rtd operation; (6)low offset drift; (7)low output current noise; (8)high psr; (9)high cmr.
