Overview

DCC
(Digital Contact Controller)
is a touch sensor IC enabling
it to convert capacitance
generated between human
body and conductive touch
pads to digital data without
any analog signal processing.
You can substitute it
for the conventional buttons
and also add scroll function
for look and feel better
design. DCC composed of
fully digital architecture
has not only provided
digital innovation in
the area of sensor signal
processing based on analog
technology but also will
be the core technology
in the ubiquitous sensor
area due to its low power
consumption and ease of
use to the variety of
applications.
It can generate touch
output almost ten times
faster than other touch
sensor ICs which gives
more flexibility for error
concealment. Its differential
signal input architecture
enables to acquire higher
immunity from common mode
noises such as RF noise.
It can also detect very
little capacitive variation
(0.03pF) so that it can
cope with versatile design
trials. In addition, its
automatic impedance calibration
enables it to maintain
consistent sensitivity
under any circumstances
such as environmental
change including temperature
and humidity or production
change including IC lot
and PCB variations.
