DESCRIPTIONThe XTR105 is a monolithic 4-20mA, 2-wire current transmit-
ter with two precision current sources. It provides complete
current excitation for platinum RTD temperature sensors and
bridges, instrumentation amplifiers, and current output cir-
cuitry on a single integrated circuit.
Versatile linearization circuitry provides a 2nd-order correc-
tion 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 un-
adjusted error of the complete current transmitter is low
enough to permit use without adjustment in many applica-
tions. 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 SO-14 surface-
mount packages and is specified for the –40°C to +85°C
industrial temperature range.
