Texas Instruments XTR115 XTR116 Datasheet
The XTR115 and XTR116 are precision current‑output converters that generate a 4‑20 mA loop signal for industrial process control, smart transmitters, and test systems. They include an on‑chip 5 V regulator for external circuitry and provide reference voltages of 2.5 V (XTR115) and 4.096 V (XTR116). The devices feature low span error (0.05 %), low non‑linearity (0.003 %), and a wide loop supply range of 7.5 V to 36 V.
Typical applications include two‑wire current loops, HART‑compatible smart sensors, voltage‑to‑current conversion, and current amplification. The datasheet details specifications, pin configuration, absolute maximum ratings, performance curves, protection methods, and mechanical dimensions for the SO‑8 package.
