FDC2212DNTR Application Field and Working Principle

The FDC2212DNTR is a low-power capacitive touch sensing controller optimized for mobile and wearable applications. It provides advanced functionalities to accurately measure touch signals, including de-noise, baseline tracking, automated calibration and more. This device integrates a patented MEAS digital core and is RoHS compliant. It has low power dissipation and is ideal for battery-powered applications.Capacitive sensing has become a popular technology in many applications such as automotive, HMI, switches, and more because it is simple to implement and offers many advantages over traditional technologies. Capacitive sensing is also advantageous in harsh environments due to its robustness to moisture and debris.The FDC2212DNTR capacitive touch sensing controller by Texas Instruments is a member of the advanced segment of capacitive sensing controllers. This controller has a 12-bit resolution and is capable of providing de-noising, baseline tracking, automated calibration and more. It is well suited for both single- and multi-touch inputs, and it is designed for applications ranging from mobile and portable devices, to automotive and HMI.The FDC2212DNTR can detect up to 12 electrodes at a time and has a built-in touch-detection algorithm that monitors the capacitance of each electrode. When the capacitance value of an electrode changes significantly from its baseline, the touch detection algorithm determines that a touch event has occurred.The FDC2212DNTR also has an advanced baseline tracking feature that helps reduce false-positive touches. The baseline tracking algorithm looks for changes and trends in the touch signals over time and adjusts the baseline values accordingly to match the new context. This ensures that the controller detects only true touch events and not false-positive ones.The FDC2212DNTR also includes an automated calibration feature that helps maintain accuracy. This feature uses an algorithm to calibrate the system and measure the noise, thereby improving accuracy and stability. The controller also offers a low-power sleep mode, allowing it to conserve energy in low-power applications.To summarise, the FDC2212DNTR is a high-performance capacitive touch sensing controller that provides advanced features including de-noise, baseline tracking and automated calibration. It is optimized for mobile and wearable applications and offers a 12-bit resolution with up to 12 electrodes. It is designed for both single- and multi-touch inputs, as well as harsh environment applications. With its low power dissipation, it is ideal for powering low-power applications.
