Overview : 

The SC12A is a self-calibrating capacitive touch sensor that detects whether or not the 12 sense discs have been touched. It can sense capacitive changes through any non-conductive medium such as glass and plastic. This capacitive sensing switch can be used in many electronic products to increase the added value of the product.

Features :

◇ 12 completely independent touch-sensitive buttons .

◇Automatic correction is maintained without external intervention .

◇ Key outputs are fully anti-dithering .

◇Multi-interface - I²C serial interface / BCD code output.

◇ All buttons share the same sensitivity capacitor .

◇ Differences in the length of the inductor line will not cause differences in sensitivity.

◇ 2.5V ~ 6.0V operating voltage .

◇ Eco-friendly SOP24 package compliant with RoHS directive.

Applications : 

◇Replacement of mechanical switches.

◇Replacement of mechanical switches .

◇Home application (TV, monitor keyboard) .

◇Human-machine interface for toys and interactive games .

◇ Door Access Keys .

◇Light Control Switches .

◇Sealed Keyboard Panels .
