They provide complete –1 current excitation for high impedance platinum RTD –200°C +850°C temperature sensors and bridges, instrumentation am- Process Temperature (°C) plifier, and current output circuitry on a single inte- grated circuit. The XTR112 has two 250μA current sources while the XTR114 has two 100μA sources for I R RTD excitation. I R V LIN Versatile linearization circuitry provides a 2nd-order V REG correction to the RTD, typically achieving a 40:1 7.5V to 36V + improvement in linearity. V PS Instrumentation amplifier gain can be configured for a 4-20 mA wide range of temperature or pressure measurements. XTR112 V Total unadjusted error of the complete current trans- R O G XTR114 mitter is low enough to permit use without adjustment in many applications. This includes zero output cur- R RTD L rent drift, span drift and nonlinearity. The XTR112 – and XTR114 operate on loop power supply voltages down to 7.5V. XTR112: I = 250μA R Both are available in an SO-14 surface-mount pack- XTR114: I = 100μA R age and are specified for the –40°C to +85°C indus- trial temperature range.
