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.
