In Part 1, we covered the basics of making capacitive sensing measurements, why capacitive sensing buttons are better than mechanical buttons, and the. ... Transition from mechanical buttons to ...

Capacitive touch sensing allows for triggering the sensor without actually physically touching one’s lips to the electrodes, which [Nathan] did by putting a clear plastic layer over the PCB traces.

A ±1,300-V/μs output slew rate into capacitive loads up to 1 nF (1000 pF). The 80-pin, 12- × 12-mm TQFP EPAD-up package greatly reduces thermal-management constraints on the PCB layout.

Once the layout is completed following the recommended values in stage 1, developers should verify their design with the aid of the tool box before moving to a PCB design. The tool box helps in ...
