Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The CAP1214 is a multiple channel Capacitive Touch sensor and LED Driver.

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. 

The CAP1214 also contains eleven (11) low side LED drivers that offer full-on / off, variable rate blinking, dimness controls, and breathing. LED outputs can be linked to capacitive sensor channels.
