XTR111AIDGQRG4

Overview

The XTR111AIDGQRG4 is a precision voltage-to-current converter and transmitter manufactured by Texas Instruments. It operates within a supply voltage range of 7V to 44V, drawing a typical quiescent current of 450µA. The device provides a regulated sub-regulator output capable of delivering up to 25mA for powering external sensors. It accepts an input voltage range of 0V to 12V and supports a maximum load resistance of 1kΩ. The component is housed in a 10-pin MSOP PowerPAD package and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Integrates a precision amplifier with a regulated power supply for sensor excitation
• Provides configurable output disable and failure detection capabilities
• Supports standard two-wire and three-wire current loop transmission protocols

Applications

• Industrial process control instrumentation
• Two-wire field transmitters
• Sensor signal conditioning circuits

Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and green material status as per Texas Instruments standards. Confirm the package type matches the design requirements, as this variant utilizes the MSOP PowerPAD form factor. Ensure the ordering part number aligns exactly with the required tape and reel specifications for automated assembly processes.

Selection Notes

Select this component when a compact solution is needed for converting low-level voltage signals into standardized current loops. The integrated regulator simplifies designs requiring simultaneous signal conversion and sensor power delivery. Consider the thermal performance of the PowerPAD package for high-temperature environments where heat dissipation is critical for maintaining accuracy.

Part Context

This device belongs to the XTR111 series of precision current transmitters designed for industrial applications. It serves as a specialized interface between voltage-based sensors and current-loop networks. The product line focuses on reducing system complexity by combining signal processing and power regulation in a single small-footprint package.

Replacement Considerations

Check for the non-RoHS version XTR111AIDGQR if environmental compliance is not required. Verify compatibility with alternative packages such as the VSON option (XTR111AIDRCT) if board space constraints differ significantly.
