XTR300EVM (TEXAS INSTRUMENTS)

The XTR300EVM is intended to provide basic evaluation of the functionality and performance of the XTR300. The XTR300 is a universal output driver for industrial and process control applications. This device can be configured as a current or voltage output device without requiring an external shunt resistor. The XTR300 requires minimal external circuitry, including a few gain setting resistors and a loop compensation capacitor. The XTR300 offers separate driver and receiver channels for improved flexibility. The internal instrumentation amplifier is normally connected for remote voltage sensing in voltage output mode. Alternatively, it can be used as a high voltage, high impedance measurement channel. In voltage output mode, a copy of the output current is provided to allow for easy testing of the load condition and eventual calculation of the load resistance. In current output mode, the load voltage can be monitored.
