Introduction

FDC1004QDGSTQ1 is an integrated capacitive sensing system designed for capacitive touch applications. It integrates an inductive sense capacitor with a shielded touch pad that detect the user\'s touch in the sensing field and communicates the information to the target application. This integrated system enables a widespread range of capacitive touch applications such as proximity sensing, user interface, and gesture recognition.

Application Field

FDC1004QDGSTQ1 is most commonly used in consumer electronics such as tablets and smart phones. With its integrated system, it is capable of detecting a variety of touch related actions and gestures, such as single, double, triple taps and swipes. This allows for easy user input, which is critical for user experience. With its capabilities, it can also be used for non-touch applications, such as proximity sensing. This can be applied to automated cleaning systems, car doors or integrated into smart home/home security systems. The possibilities are endless.

Working Principle

FDC1004QDGSTQ1 has an integrated capacitance-to-digital converter which senses the capacitance in the target area. This capacitance is the change in electric field due to the user\'s touch. This electric field is measured by the converter and transmitted to the target application. The integrated system also includes a shielded sensor for noise immunity, which helps ensure accuracy in the measurements. The integrated system also includes an I2C interface which allows for fast data exchange between the target application and the converter. This allows for fast response time and accurate data exchange.

Conclusion

FDC1004QDGSTQ1 is an integrated capacitive sensing system designed for capacitive touch applications. Its integrated system, along with its noise immunity, allow for easy user input while also providing accuracy and fast response time. It is most commonly used in consumer electronics such as tablets and smart phones and can be used in a variety of non-touch applications such as proximity sensing.
