Production Description:
1.General Description
The integrated circuit MS8883A 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
