FDC2114RGHT

Overview

The FDC2114RGHT is a four-channel capacitive-to-digital converter manufactured by Texas Instruments. It features a WQFN-16 package and operates within a supply voltage range of 2.7 V to 3.6 V. The device provides 28-bit resolution and supports output rates up to 13.3 ksps. It utilizes an I2C interface with a maximum clock frequency of 400 kHz. The component functions across a temperature range from -40°C to +125°C.

Feature Summary

• High-resolution capacitive sensing with 28-bit precision
• Anti-EMI architecture for stable performance in noisy environments
• Wide excitation frequency range supporting various sensor types

Applications

• Non-contact proximity sensors
• Liquid level detection
• Gesture recognition systems

Procurement Notes

Verify the specific suffix 'RGHT' against the manufacturer's official documentation to confirm the tape and reel packaging configuration. Ensure the order matches the exact part number to avoid receiving alternative package variants such as WSON or cut tape versions. Cross-reference the datasheet revision date to ensure compatibility with current design requirements.

Selection Notes

Select this component when high resolution and anti-EMI performance are required for capacitive sensing applications. It is suitable for designs needing operation at temperatures up to 125°C. Compare it against the FDC2214 if lower output rates but different noise characteristics are acceptable, or against the LDC2114 for inductive sensing needs.

Part Context

This device belongs to the FDC2x1x series of capacitive digital converters designed for robust operation in electromagnetic interference (EMI) environments. The series includes models like the FDC2112, FDC2212, and FDC2214, offering varying channel counts and performance trade-offs while maintaining consistent interface and power specifications.

Replacement Considerations

Publicly confirmed substitutes include the FDC2114EVM evaluation module contextually related to development, or other members of the FDC2x1x family such as the FDC2112 for two-channel applications. Verify pinout and register compatibility before substituting.
