XTR105 pdf datasheet (4-20mA, two-wire current transmitter)

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, 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.

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.

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.
