The XTR112 and XTR114 are monolithic 4-20mA,two-wire current transmitters. They provide completecurrent excitation for high impedance platinum RTDtemperature sensors and bridges, instrumentation am-plifier, and current output circuitry on a single inte-grated circuit. The XTR112 has two 250µA currentsources while the XTR114 has two 100µA sources forRTD excitation.Versatile linearization circuitry provides a 2nd-ordercorrection to the RTD, typically achieving a 40:1improvement in linearity.Instrumentation amplifier gain can be configured for awide range of temperature or pressure measurements.Total unadjusted error of the complete current trans-mitter is low enough to permit use without adjustmentin many applications. This includes zero output cur-rent drift, span drift and nonlinearity. The XTR112and XTR114 operate on loop power supply voltagesdown to 7.5V.
