(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported.
(2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current limited.
(3) See the Driver Output Disable section in Application Information section for thermal protection.

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 XTR300 separate driver and receiver channels provide flexibility. The Instrumentation Amplifier (IA) can be used for remote voltage sense or as a high-voltage, highimpedance 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 of XTR300 provide continuous feedback about load power or impedance. For additional protection, the maximum output current is limited and thermal protection is provided.

Digital communication like HART can be modulated onto the input signal. The receive signal applied to the output can be detected at the monitor pins in both current and voltage output modes. In addition to HART communication, the device offers system or sensor configuration through the signal connector.The XTR300 is specified over the −40 to +85 industrial temperature range and for supply voltage up to 40V.
