Description
The XTR105 is a monolithic 4mA to 20mA, 2-wire
current transmitter with two precision current sources.
This device 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.
The XTR105 is available in DIP-14 and SOIC-14
surface-mount packages and is specified for the
industrial temperature range of –40°C to +85°C.
