4mA-to-20mA Current-Loop, Texas Instruments


The Texas Instruments 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.
