XTR305IRGWR

Overview

The XTR305IRGWR is a Texas Instruments analog current and voltage output driver designed for industrial sensor interfaces. It operates on a single supply voltage ranging from 5 V to 22 V, with a typical operating supply current of 1.8 mA. The device provides a reference voltage of 4 V and features an input bias current of 20 nA. It supports a maximum output current of 20 mA and can drive up to 10 V. Housed in a 20-VQFN package with an exposed pad, it includes ESD protection and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Configurable as either a current or voltage output driver without requiring external current shunt resistors.
• Integrated 4 V precision reference voltage and low input bias current (20 nA) for high-accuracy signal conditioning.
• Built-in diagnostic capabilities including short-circuit and open-load fault indication pins.
• Supports asymmetric power supplies and drives large capacitive loads.

Applications

• Motor drive analog outputs
• PLC output programmable drivers
• Industrial cross-connectors
• High-voltage I/O systems

Procurement Notes

Verify the specific suffix 'RGWR' corresponds to the 20-VQFN package and tape & reel packaging format. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure handling procedures account for moisture sensitivity classification during storage and assembly.

Selection Notes

Select this component when interfacing low-voltage digital domains with high-voltage industrial signals. The 20-VQFN package requires adequate thermal management due to the exposed pad design. Verify that the required output swing and load capacitance fall within the specified operational limits of the device.
