XTR116 Datasheet Current-loop Transmitters

Manufacturer: Texas Instruments

Overview: XTR115, XTR116 SBOS124B – JANUARY 2000 – REVISED JUNE 2023 XTR11x 4-20 mA Current-Loop Transmitters.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The XTR115 and XTR116 (XTR11x) are precision current output converters designed to transmit analog 4-mA-to-20-mA signals over an industry standard current loop.

These devices provide accurate current scaling and output current limit functions.

The on-chip voltage regulator (5 V) can be used to power external circuitry.
