4-20mA Current Loop Transmitters

4-20mA Current Loop Transmitters - XTR115
 

Recommended alternative parts

  • XTR116  -  On-chip 4.096V voltage reference instead of 2.5V reference.
  • XTR117  -  Lower supply current. Wider supply range. Does not include voltage reference.
  • XTR106  -  Includes 2.5V and 5V voltage reference. 5.1V regulator instead of 5V.

Description

The XTR115 and XTR116 are precision current output converters designed to transmit analog 4-to-20mA signals over an industry standard current loop. They provide accurate current scaling and output current limit functions.

The on-chip voltage regulator (5V) can be used to power external circuitry. A precision on-chip VREF (2.5V for XTR115 and 4.096V for XTR116) can be used for offsetting or to excite transducers. A current return pin (IRET) senses any current used in external circuitry to assure an accurate control of the output current.

The XTR115 is a fundamental building block of smart sensors using 4-to-20mA current transmission.

The XTR115 and XTR116 are specified for operation over the extended industrial temperature range, -40°C to +85°C.
