DESCRIPTION
The XTR103 is a monolithic 4-20mA, two-wire
current transmitter designed for Platinum RTD tem-
perature sensors. It provides complete RTD current
excitation, instrumentation amplifier, linearization, 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 measurements. Total
adjusted error of the complete current transmitter,
including the linearized RTD is less than
±
1% over the
full –40 to +85
°
C operating temperature range. This
includes zero drift, span drift and nonlinearity. The
XTR103 operates on loop power supply voltages down
to 9V.
The XTR103 is available in 16-pin plastic DIP and
SOL-16 surface-mount packages specified for the
–40
°
C to +85
°
C temperature range.
