XTR115UA/2K5

XTR115UA/2K5 is the tape-and-reel SOIC-8 ordering code for the Texas Instruments XTR115 4-20 mA current-loop transmitter, listed by TI as Active / Production in the datasheet ordering appendix (Rev. C) for this /2K5 reel variant itself - the unsuffixed tube code XTR115U in the same appendix is obsolete, and its status does not transfer. It runs from a 7.5 V to 36 V loop supply, converts against an internal 2.5 V reference (the 4.096 V reference belongs to the XTR116 family member, not this code), holds span error to 0.05 % maximum and nonlinearity error to 0.003 %, draws 200 µA typical quiescent current, shows input offset voltage of 0.25 mV maximum with drift of 3 µV/°C maximum, and provides a 5 V regulated output to power external input circuitry. The selection point is a two-wire transmitter front end with the reference and regulator already inside: pressure, temperature and level transmitters ship with fewer external parts and a documented error budget. Selection advice: quote the UA/2K5 suffix in full - it is the active reel variant, and offers of the unsuffixed code carry a different lifecycle status. Parameters verified against the TI XTR115 datasheet SBOS124 and the current ordering appendix.
