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.
