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.
