Overview
The XTR300AIRGWR is a comprehensive industrial analog current/voltage output driver produced by Texas Instruments. This component is designed for industrial and process control applications, offering the flexibility to configure the output as either current or voltage via a digital I/V select pin. It does not require an external shunt resistor, needing only external gain-setting resistors and a loop compensation capacitor for operation. The XTR300 features separate driver and receiver channels, enhancing its versatility and functionality. It includes an Instrumentation Amplifier (IA) that can be used for remote voltage sensing or high-voltage, high-impedance measurements. The device is specified over an industrial temperature range of −40°C to +85°C and supports supply voltages up to 40V.
