IQS223 DATASHEET
3 Channel capacitive proximity and touch controller with flick or swipe and tap & hold gesture outputs
The IQS223 ProxSense® IC is a 3-channel self/projected capacitive proximity and touch controller
with best in class sensitivity, signal to noise ratio and power consumption. Other features include
automatic tuning of the sense electrodes, internal reference capacitor and an internal regulator to
reduce total system cost.
RoHS & Reach Compliant
Main Features
