LDC1612: touch panel implementation on glass

Vincenzo Pizzolante

Part Number: LDC1612
Other Parts Discussed in Thread: LDC1614, TIDA-01102

hi

with a customer we are discussing a new marine product for the external use.

The keypad/board will be printed on glass, but touchscreen or capacitive touch does not come in questions, because it is hard or impossible to operate it, when water is present and sometimes you can press the touch button by mistake as well. 

So he is looking now at LDC1612.

is this the best solution?

any advice is more than welcome...

thansk a lot in advance

KR

    Hi Vincenzo,

    To use inductive sensing for this application, the customer would need to have a metal target. They could possibly add metal to the back of their glass keypad, but I'm not sure that the glass will be elastic enough to create a functional keypad.

    If it's possible to use a metal target, either the LDC161x devices or the LDC211x devices would be best suited for this application. I would recommend looking at the Touch-on-Metal Keypad reference design (TIDA-01102), which used the LDC1614. The LDC211x devices are specifically design for button applications, so this may be an option for the customer as well.

    Regards,
