Overview
The FDC2214RGHT is a four-channel capacitance-to-digital converter manufactured by Texas Instruments. It features a 28-bit resolution and operates within a supply voltage range of 2.7V to 3.6V. The device supports an I2C interface and functions at temperatures between -40°C and +125°C. It utilizes a 16-pin WQFN package with dimensions of 4mm x 4mm. The component is designed for high-precision sensing applications requiring robust performance in noisy environments.
Feature Summary
- High-resolution 28-bit capacitance measurement capability
- Integrated anti-EMI architecture for stable operation in noisy conditions
- Supports multiple sensor types including capacitive touch and proximity detection
Applications
- Capacitive touch sensing interfaces
- Proximity detection systems
- Liquid level measurement
Procurement Notes
Verify the specific suffix 'RGHT' against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements and I2C bus configurations before integration. Cross-reference datasheet revisions to validate pinout assignments and electrical characteristics.
Selection Notes
Select this component when high precision and EMI immunity are required for non-contact sensing. Compare channel count and resolution against alternatives like the FDC2212 if fewer channels suffice. Evaluate power consumption metrics against battery life requirements, noting the low-power shutdown modes available in the series.
Part Context
This part belongs to the FDC2x1x family of capacitance-to-digital converters from Texas Instruments. The family includes variants such as the FDC2212, FDC2112, and FDC2114, which share similar architectural features but differ in channel counts and output rates. This specific model provides four dedicated input channels for simultaneous sensing operations.
Replacement Considerations
The FDC2214QRGHRQ1 is an automotive-grade variant within the same functional family. Verify if AEC-Q100 certification is necessary for the target application. Other family members like the FDC2212 offer two channels, which may require design adjustments if channel count is not critical.
