Hi all,
I am not sure if it is the correct place to post, as it is analog circuit, I thought here to post it.
I am designing a circuit where 3 capacitive touch input is required. I found TTP224 is reasonable for me. However, the problem is It has 4 Touch input. Can any one suggest me what is the best way to terminate the fourth touch input? I found that if I leave it floating, it is in most sensitive condition. I am thinking to use the high rated capacitor of 100pF with GND to terminate it. Is this right process to do it?
Thanks to all.
