描述 Description

The IQS316 is a 16 channel self capacitive touch and proximity controller with advanced on-chip signal processing features, including Auto Tuning (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.
