Low-power, high-sensitivity, environmentally robust capacitive touch buttons,
sliders, and wheels
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 VDD range
Auto calibration and recalibration of sensors
Single-shot charge measurement
Hardware noise filtering and noise signal desynchronization for high conducted
immunity
Polarity control, allowing Parallel Acquisition (through the QTouch Library)
individually controls the polarity of each line
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
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
