XTR300 (ACTIVE) Industrial Analog Current/Voltage Output Driver

 

Recommended alternative parts

  • XTR111  -  The XTR111 is made for unipolar output, can only source current and needs to be hard wired for current or voltage. It is also lower cost and single supply.
  • XTR110  -  The XTR110 is similiar to the XTR111, but includes a 10V reference instead of of a voltage regulator.

Description

The XTR300 is a complete output driver for industrial and process control applications. The output can be configured as current or voltage by the digital I/V select pin. No external shunt resistor is required. Only external gain-setting resistors and a loop compensation capacitor are required.

The separate driver and receiver channels provide flexibility. The Instrumentation Amplifier (IA) can be used for remote voltage sense or as a high-voltage, high-impedance measurement channel. In voltage output mode, a copy of the output current is provided, allowing calculation of load resistance.

The digital output selection capability, together with the error flags and monitor pins, make remote configuration and troubleshooting possible. Fault conditions on the output and on the IA input as well as over-temperature conditions are indicated by the error flags. The monitoring pins provide continuous feedback about load power or impedance. For additional protection, the maximum output current is limited and thermal protection is provided.

The XTR300 is specified over the −40°C to +85°C industrial temperature range and for supply voltages up to 40V.
