AW93006DNR数据手册Awinic中文资料规格书

描述 Description

AW93006DNR is a 6-channel low power consumption capacitive touch and proximity controller. Each channel can be independently configured as sensor input, shield output.Advanced self-capacitance technology is adopted, which supports parasitic capacitance compensation for each channel up to 220pF. The device has a high resolution ADC, the minimal capacitance that can be detected is as low as 1aF.A high performance 32bit MCU is integrated by executing the firmware-program in the ROM, it implements all AFE sampling controlling and complicated data processing algorithms including signal filtering, RF noise suppression, baseline calculation, proximity status decision, etc.With the auxiliary of DSP algorithm, the device is able to track slow environmental variations (such as temperature, humidity, etc.) and maintain high performance operation.
