2) AW93805QNR: QFN 3×3-24L
AW93804/AW93805 is a force/capacitive sensing which supports up to 4/5-channel force or 10/12-channel capacitive detection and mainly used for wear detection, touch key, linear slider, wheel slider, etc.
Advanced force technology is adopted in AW93804/AW93805. With a high-resolution ADC and advanced digital signal processing (DSP) algorithm.
Advanced self/mutual capacitance technology is adopted in AW93804/AW93805. With a high-resolution ADC and advanced digital signal processing (DSP) algorithm, the minimal capacitance that can be detected is as low as 1aF in typical application.
AW93804/AW93805 contains the I2C serial communication bus. Through I2C, Host can configure the chip to work. Upon event detection, the interrupt pin outputs asserts, enabling Host to receive the event information such as distance.
A built-in ultra-low power MCU realizes AFE sampling control, signal filtering, RF noise suppression, adaptive temperature compensation, baseline tracking, touch/wearing status determination, etc.
With the advanced DSP algorithm, AW93804/AW93805 is able to track gradual environmental variations (such as temperature, humidity, etc.).
AW93804/AW93805 can recognize various gestures, such as single/double/triple click, short/long press, linear slide and wheel slide with the high-resolution force/capacitive sensing. The chip integrates force/capacitive technology and dedicated algorithm, which greatly improve the waterproof performance for touch key.
