16 AND 24 KEY QMATRIX™ TOUCH SENSOR ICs
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.
