Product 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
