Product Summary

The XTR105PA 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

XTR105PA absolute maximum ratings: (1)Power Supply, V+ (referenced to IO pin): 40V; (2)Input Voltage, VIN, VIN (referenced to IO pin): 0V to V+; (3)Storage Temperature Range: –55℃ to +125℃; (4)Lead Temperature (soldering, 10s): +300℃; (5)Output Current Limit: Continuous; (6)Junction Temperature: +165℃.

Features

XTR105PA features: (1)low unadjusted error; (2)two precision current sources 800mA each; (3)RTD or bridge excitation; (4)linearization; (5)two or three-wire rtd operation; (6)low offset drift: 0.4mV/℃; (7)low output current noisE: 30nAp-p; (8)high PSR: 110dB min; (9)high CMR: 86dB min; (10)wide supply range: 7.5V TO 36V; (11)14-pin DIP and SO-14 SOIC packages.
