XTR116U

Sensor And Detector Interfaces Overview

The XTR116U is a precision current loop transmitter manufactured by Texas Instruments, designed for industrial sensor interfaces. It converts an input voltage signal into a standard 4-20mA current output suitable for two-wire systems. The device integrates a regulated 5V supply to power external sensors or microcontrollers via the VREG pin. Key electrical parameters include a supply voltage range of 7.5V to 36V and a maximum operating temperature of 85°C. It utilizes an 8-SOIC surface-mount package with a width of 3.90mm. The component operates within a specified ambient temperature range of -40°C to 85°C and supports a supply current of 20 mA.
