PRODUCT FEATURES

General Description

T h e C A P 111 4 , w h i c h i n c o r p o r a t e s S M S C ’ s

RightTouch

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.
