IQ Switch^® - ProxSense^® Series
Multi-channel Capacitive Sensing Controller with Advanced Signal Processing Functions
The IQS316 is a 20 channel surface capacitive touch and proximity controller with advanced on-
chip signal processing features, including Antenna Tuning Implementation (ATI). Proximity
detection can be distributed over all keys, or only selected keys, providing high flexibility for stable
operation in varying designs. The controller is based on patented capacitive sensing technology
that yields stability with high sensitivity and excellent noise immunity. This controller can operate
with a small number of external components to provide a low cost solution for medium to high
channel count applications.
