General Description
The CAP1214 is a multiple channel Capacitive Touch sensor and LED Driver.1
The CAP1214 contains up to fourteen (14) individual Capacitive Touch sensor inputs with programmable sensitivity for use in touch button and slider switch applications. Each sensor input contains automatic recalibration with programmable time delays.
The CAP1214 includes compensation circuitry that provides uniform touch sensitivity across a wide range of external sensing pad capacitance.
