Texas Instruments  XTR305IRGWR

The XTR305 is a complete output driver for cost-sensitive industrial and process controlapplications. The output can be configured as current or voltage by the digital I/V select pin. Noexternal shunt resistor is required. Only external gain-setting resistors and a loop compensationcapacitor are required.

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

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

The XTR305 is specified over the −40°C to +85°C industrial temperature range and forsupply voltages up to 40 V, and is operational over the extended industrial temperature range(−55°C to +125°C).
