TI - Low-power, low-cost, high-resolution contactless sensing can be applied to variety of applications (FDC2112QDNTRQ1)

 Texas Instruments FDC2x1x-Q1 is a multi-channel series of high-resolution, high-speed, capacitive-to-digital converters that resist noise and EMI for implementing capacitive sensing solutions. The device uses an innovative narrowband-based architecture that provides high noise and interference rejection while providing high speed and high resolution. The device supports a wide range of excitation frequencies, providing flexibility in system design. Capacitive sensing is a low-power, low-cost, high-resolution non-contact sensing technology that can be applied to a variety of applications from proximity detection to gesture recognition. The sensors in a capacitive sensing system can be any metal or conductor, enabling a low-cost and highly flexible system design. The main challenge limiting the sensitivity in capacitive sensing applications is the sensor's noise sensitivity. Utilize the device's innovative EMI-resistant architecture to maintain performance even in high-noise environments.
