IS31SE5104 Даташит - Integrated Silicon Solution

GENERAL DESCRIPTION
The IS31SE5104 is an ultra low power, fully integrated 4-channel solution for capacitive touch-buttons applications. The chip allows electrodes to project sense fields through any dielectric such as glass or plastic. On-chip calibration logic continuously monitors the environment and automatically adjusts on-and-off threshold levels to prevent false sensor activation.

FEATURES
● Complete eight sensors capacitive touch
