Device Overview

Summary

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

Additional Features
  • 6 Capacitive Touch Sensor Inputs
  • 2 LED Driver Outputs
  • Programmable sensitivity
  • Automatic recalibration
  • Individual thresholds for each button
  • Proximity Detection
  • Multiple Button Pattern Detection
  • Analog Filtering for System Noise Sources
