5 Summary

Inductive touch buttons implemented using the LDC211x and LDC3114 can be tuned to precise amounts of button activation force with relative ease. The process to tune the button activation force requires a correctly configured LDC211x or LDC3114 and an adjustment of the gain configuration. This document went over the steps required to tune an inductive touch button to a precise amount of force.
