AT42QT2640数据手册集成电路（IC）的传感器电容式触控规格书PDF

描述 Description

The Microchip'sAT42QT2640 is a capacitive touch controller with configurable 64-QTouch buttons. The Microchip QMatrix sensing algorithm (mutual capacitance) enables the user to achieve more buttons than there are pins because of this matrix layout. The device includes all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions and frequencies.

UL and IEC certified according to IEC/EN 60730 (Ed. 4.0) / IEC/EN 60335 (Ed. 5.0) for Appliance safety class B.
