Overview : 

The SC09B is a self-correcting capacitive sensor that detects whether or not the 9 sense discs have been touched. It can sense capacitive changes through any non-conductive medium such as glass and plastic. This capacitance sensing switch can be used in many electronic products to increase the added value of the product.

 Features :

◇ 9 completely independent touch-sensitive buttons .

◇Automatic calibration is maintained without external intervention.

◇The key outputs are completely de-jittered.

◇ I²C serial interface .

◇ All keys share a common sensitivity capacitor .

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

◇ 2.5V ~ 6.0V operating voltage .

◇ Eco-friendly SOP16 package compliant with RoHS Directive .

Applications：

◇Replacement of mechanical switches .

◇Home application (TV, monitor keyboard) .
