Texas Instruments LDC1314KEYPAD-EVM
The LDC1314's unique inductive sensing capability is used to implement a contactless, 16 button, multi-function keypad. It uses standard PCB technology and easily manufactured components to implement a low cost solution.
This design uses the LDC1314 and can also be used with LDC1312, LDC1612 and LDC1614.
