Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix RGH indicates the correct package type and tape-and-reel configuration. Confirm AEC-Q100 certification status through official Texas Instruments documentation or authorized distributor datasheets before integration into production designs.

Sensor And Detector Interfaces Selection Notes

Select this model when 28-bit resolution is required for small capacitance changes. Ensure the design accommodates the 2.7V to 3.6V supply range. Verify that the 16-pin WFQFN footprint matches the PCB layout constraints and thermal requirements of the target application.

Sensor And Detector Interfaces Part Context

This part belongs to the FDC2114 family of capacitive sensors. It shares functional similarities with other members like the FDC2112 but offers higher channel count and resolution. The Q1 suffix denotes automotive grade qualification, distinguishing it from commercial variants.

Sensor And Detector Interfaces Replacement Considerations

Direct substitutes include other FDC211x series devices such as FDC2112QRGHTQ1 if fewer channels are acceptable. Verify pin compatibility and software register mapping differences between specific sub-models before swapping.
