These devices require only a common inexpensive capacitor per sensing channel in order to function. They also offer patent pending AKSTM Adjacent Key Suppression which suppresses touch from weaker responding keys and allows only a dominant key to detect, for example to solve the problem of large fingers on tightly spaced keys. These devices also have a SYNC I/O pin which allows for synchronization with additional similar parts and/or to an external to suppress interference. |
