Low-power, high-sensitivity,
environmentally robust capacitive touch buttons, sliders, and wheels
Driven Shield Plus for better noise immunity and moisture tolerance
Any PTC X/Y line can be used for the driven shield
All enabled sensors will be driven at the same potential as the sensor
scanned
Supports wake-up on touch from standby Sleep mode
Supports mutual capacitance and self-capacitance sensing
Mix-and-match mutual-and
self-capacitance sensors
One pin per electrode – no external components
Load compensating charge sensing
Parasitic capacitance compensation and adjustable gain for superior sensitivity
Zero drift over the temperature and
AVDD range
Auto calibration and
recalibration of sensors
Single-shot and free-running charge
measurement
Hardware noise filtering and noise
signal desynchronization for high conducted immunity
Polarity control, allowing Parallel
Acquisition (through the Touch Library) individually controls the polarity of each
line
Selectable channel change delay allows
choosing the settling time on a new channel, as required
Acquisition-start triggered by command
or through auto-triggering feature
Low CPU utilization through interrupt
on acquisition-complete
