XTR111 - Precision Voltage-to-Current Converter/Transmitter

General Description

The XTR111 is a precision voltage-to-current converter designed for the standard 0mA to 20mA or 4mA to 20mA analog signals, and sources up to 32mA.

The ratio between input voltage and output current is set by a single resistor, RSET.

The circuit can also be modified for voltage-output operation.

Key Features

  • Easy-to-design input/output ranges: 0mA.
  • 20mA, 4mA.
  • 20mA, 5mA.
  • 25mA or configurable voltage outputs.
  • Nonlinearity: 0.002%.
  • Low offset drift: 1μV/°C.
  • Accuracy: 0.015%.
  • Single-supply operation.
  • Wide supply range: 7V to 44V.
  • Output error flag (EF).
  • Output disable (OD).
  • Adjustable voltage regulator: 3V to 15V.
  • Packages:.
  • 10-pin HVSSOP.
  • 10-pin VSON 2.
