Hi Expert,

When I press the "signal conditioners" link, I can't find any LDC serials products, Why? Does any plan change it to NRND part? Thanks!

They are not showing up in the parametric search; however, there are no current plans to NRND this part.

Hi Clancy,
Thanks for the information. Does LDC1101 suitable in phone metal touch application? The touch area is 3mm*20mm, is it OK for the design?
Can you share more experience for it? Thanks!

The LDC2112 or LDC2114 are probably your best options for phone metal touch applications. Those devices are designed for button applications and have integrated algorithms that make things simpler for the designer.

Hi Clancy,
I found the example in "www.ti.com/.../snaa307.pdf". Do you have the LDC sensor size? The touch area is 3mm*20mm, is it OK for the design? Thanks!

Jerry, that should be possible, but it will be limited based on your PCB manufacturer's capabilities. You can use the LDC calculator tool to estimate how small your trace widths will need to be to achieve a sensor of that size.
