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.
