TTP226 is a capacitive touch sensing IC with low cost and high stability, providing eight sensing electrodes. It can replace the traditional direct button with fixed size. It has three ways, such as direct output, matrix output and serial output. It is ideal for different kind of consumer electronics and appliances, such as MP3,MP4,PDA, digital photo frame, DVR and so on. The sensing button in the application of DC and AC has the below characteristics: low power consumption, wide working voltage and high sensing distance.
