XTR117AIDGKT

Sensor And Detector Interfaces Overview

The XTR117AIDGKT is a voltage-input, current-output transmitter integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 7.5 V to 40 V and draws a typical operating supply current of 130 µA. The device features an internal precision reference and is designed for industrial process control applications requiring high accuracy. It is housed in an 8-VSSOP package with a width of 3.00 mm. The component supports surface mount installation and functions reliably across an extended temperature range from -40°C to +125°C. This specific part number has been declared obsolete with a discontinuation notice dated September 2, 2023.

Sensor And Detector Interfaces Procurement Notes

This component is officially obsolete and no longer in production as per the Product Change Notification dated September 2, 2023. Verification of authenticity is critical when sourcing remaining stock from third-party distributors. Buyers must confirm the specific lot date code and ensure the device has not exceeded its moisture sensitivity level limits prior to soldering. Replacement strategies should prioritize the manufacturer-recommended alternative to ensure long-term supply stability.

Sensor And Detector Interfaces Selection Notes

Designers should evaluate the XTR117AIDGKR as the primary active replacement, which shares the same 8-VSSOP footprint and electrical characteristics. The selection depends on verifying that the application does not require the exact tape-and-reel packaging of the discontinued DGKT variant. Engineers must also assess if the broader XTR11x family meets the specific accuracy and temperature drift requirements of the target system.

Sensor And Detector Interfaces Part Context

The XTR117 belongs to the XTR11x series of current loop transmitters from Texas Instruments. This series is widely utilized in industrial automation for converting low-level sensor signals into standardized 4-20mA outputs. The XTR117 specifically targets voltage-input applications, distinguishing it from other variants in the family that may support different input types or packaging options like SOIC or SON.

Sensor And Detector Interfaces Replacement Considerations

The XTR117AIDGKR is the manufacturer-recommended substitute. It maintains identical pinout and functionality but is available in active production status.
