Production Description:

1.General Description
    The integrated circuit MS8883C is a capacitive switch that uses a patented (EDISEN) digital method to detect a change in capacitance on a remote sensing plate.
    Changes in the static capacitance (as opposed to dynamic capacitance changes) are automatically compensated using continuous auto-calibration. Remote sensing plates (e.g. conductive foil) can be connected remotely to the IC using coaxial cable.
 
2.Applications

•  Hermetically sealed keys on a keyboard
•  Switch for medical applications
•  Switch for use in explosive environments
•  Vandal proof switches
•  Automotive: Switches in or under upholstery, leather, handles, mats and glass
•  Portable entertainment units
•  Buildings: Switch in or under carpets, glass or tiles
•  Sanitary applications: Use of standard metal sanitary parts (e.g. tap) as switch
