XTR117 - 4-20mA Current-Loop Transmitter

General Description

The XTR117 is a precision current output converter designed to transmit analog 4-mA-to-20-mA signals over an industry-standard current loop.

The device provides accurate current scaling and output current limit functions.

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

Key Features

  • Low quiescent current: 130 µA.
  • 5‑V regulator for external circuits.
  • Low span error: 0.05%.
  • Low nonlinearity error: 0.003%.
  • Wide-loop supply range: 7.5 V to 36 V.
  • Temperature range:.
  • 40°C to +125°C.
  • Packages: VSON-8 and VSSOP-8 2.
