Overview

The LDC1314KEYPAD evaluation module implements a 16 snap dome button keypad using only one LDC1314 to multiplex all 16 buttons.

This design uses the LDC1314 but can also be replicated with the LDC1312, LDC1612 and LDC1614.

Features
  • Contactless buttons, with superior reliability over electrical/mechanical contact solutions
  • Can be easily used to implement ruggedized, environmentally sealed keypad and keyboard solutions for harsh environments
  • Supports simultaneous button presses
  • Temperature stable
  • Easily scalable to larger key arrays
