16 AND 24 KEY QMATRIX™ TOUCH

ENSOR IC

These devices are designed for low cost mobile and consumer electronics

applications.

QMatrix™ technology employs transverse charge-transfer sensing electrode

designs which can be made very compact and are easily wired. Charge is

forced from an emitting electrode into the overlying panel dielectric, and then

collected on a receiver electrode which directs the charge into a sampling

capacitor which is then converted directly to digital form without the use of

amplifiers.

Keys are configured in a matrix format that minimizes the number of required

scan lines and device pins. The key electrodes can be designed into a

conventional Printed Circuit Board (PCB) or Flexible Printed Circuit Board

(FPCB) as a copper pattern, or as printed conductive ink on plastic film.
