The XTR115 and XTR116 are precision current outputconverters designed to transmit analog 4-to-20mAsignals over an industry standard current loop. Theyprovide accurate current scaling and output currentlimit funcTIons.The on-chip voltage regulator (5V) can be used topower external circuitry. A precision on-chip VREF(2.5V for XTR115 and 4.096V for XTR116) can beused for offsetTIng or to excite transducers. A currentreturn pin (IRET) senses any current used in externalcircuitry to assure an accurate control of the outputcurrent.The XTR115 is a fundamental building block ofsmart sensors using 4-to-20mA current transmission.The XTR115 and XTR116 are specified for operaTIonover the extended industrial temperature range,–40°C to +85°C.
