DESCRIPTION

The XTR105 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, instrumenta-

tion amplifier, and current output circuitry on a single

integrated circuit.

_R= 0.8mA

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 trans-

mitter is low enough to permit use without adjustment

in many applications. This includes zero output cur-

rent drift, span drift and nonlinearity. The XTR105

operates on loop power supply voltages down to 7.5V.

The XTR105 is available in 14-pin plastic DIP and

SO-14 surface-mount packages and is specified for the

–40°C to +85°C industrial temperature range.
