GENERAL DESCRIPTION
AW96205DNR is a 5-channel low-power capacitive touch and proximity controller. Each channel can be independently configured as sensor input, shield output.
Advanced self-capacitance technology is adopted in AW96205DNR. For the device has a high-resolution ADC, the minimal capacitance that can be detected is as low as 1aF.
AW96205DNR integrates a ultra-low-power MCU, by executing the algorithm program in the FLASH, it implements diversified analog front end (AFE) sampling controlling and complicated data processing algorithms including signal filtering, RF noise suppression, baseline calculation, proximity detection, etc.
With the auxiliary of DSP algorithm, the device is able to track gradual environmental variations (such as temperature, humidity, etc.) and maintain high performance operation.
