Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix RGH indicates the QFN-16 package and HRQ1 denotes automotive grade and tape-and-reel packaging. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the supplier provides valid traceability records for automotive components. Cross-reference the full part number against the latest Texas Instruments datasheet to confirm pinout and electrical specifications match the design requirements.

Sensor And Detector Interfaces Selection Notes

Select this component when designing systems requiring high-resolution capacitance sensing in automotive environments. The 28-bit resolution supports fine detection sensitivity for small displacement or proximity changes. The wide operating temperature range ensures functionality under extreme engine bay or exterior conditions. Verify that the host microcontroller supports the required I2C protocol and voltage levels compatible with the 2.7 V to 3.6 V supply range.

Sensor And Detector Interfaces Part Context

This device belongs to the FDC2214/FDC2114 family of capacitance-to-digital converters from Texas Instruments. While the FDC2214 offers higher resolution for larger capacitive ranges, the FDC2114 series is optimized for smaller capacitance values typical in touch and proximity applications. The QRGHRQ1 variant specifically targets automotive markets with enhanced reliability standards compared to commercial counterparts.

Sensor And Detector Interfaces Replacement Considerations

Direct replacements include other AEC-Q100 qualified capacitance-to-digital converters from Texas Instruments such as the FDC2214QRGHRQ1, noting differences in resolution and input capacitance range. Non-TI equivalents require careful evaluation of interface compatibility, resolution, and automotive certification status.
