Capacitive Touch Controllers for Buttons, Sliders and Wheels
Atmel® offers market-proven
technology for implementing
nonmechanical buttons, sliders,
and wheels on any touch-sensitive
device. These integrated circuits
(ICs) enhance the user experience
with excellent precision and
reliability. They also deliver superb
low-power characteristics, a critical
requirement for today’s battery-
powered handheld and mobile
devices. The technology supports
simple 1–10 button configurations
(self capacitance) as well as
more complex scanned-matrix
configurations (mutual capacitance)
of up to 48 buttons at very low
cost per button. In addition to the
application specific chips, Atmel
offers the QTouch® Library for
embedding buttons, sliders, and
wheels into the industry-leading
AVR® microcontrollers and Atmel
AT91SAM.
