16 AND 24 KEY QMATRIX™ TOUCH SENSOR ICs
SCL /RST Y0A Y2B SMP SDA Y1A Y2A
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.
