CAP1126

In Production

The CAP1126 is a turnkey capacitive touch controller providing a wide variety of  button and proximity functionality, and making it easy for designers to add  aesthetically pleasing, low-cost and robust touch interfaces.  The CAP1126 also contains 2 LED drivers that offer full-on / off, variable rate blinking, dimness controls, and breathing. Each of the LED drivers may be linked to one of the sensor inputs to be actuated when a touch is detected. As well, each LED driver may be individually controlled via a host controlle...
