Digital Capacitive Switch 16 Channel TTP229

Capacitive Switch 16 Channel description.

• The TTP229 is capacitive sensing design specifically for touch pad controls.
• The device has a built in regulator for the touch sensor.
• Stable sensing method can cover diversity conditions. Interface control panel links through non-conductive dielectric material.
• The main application is focused at replacing of the mechanical switch or button. This board can independently handle the 16 touch pads with 16 direct output pins.
