CAP1114 Multiple Channel Capacitive Touch Sensor and LED Driver PRODUCT FEATURES Datasheet General Description The CAP1114, which incorporates SMSC’s RightTouchTM1 technology, is a multiple channel Capacitive Touch sensor and LED Driver. The CAP1114 contains up to fourteen (14) individual Capacitive Touch sensor inputs with programmable sensitivity for use in touch button and slider switch applications. Each sensor also contains automatic recalibration with programmable time delays. The CAP1114 also includes internal circuitry to compensate for design and parasitic variance in un- touched capacitance on sensors. The CAP1114 also contains eleven (11) low side LED drivers that offer full-on / off, variable rate blinking, dimness controls, and breathing. Capacitive buttons can be linked to LED outputs.
