Product Summary
IMPORTANT NOTEThe following products are no longer recommended for new designs: - QT100, QT110, QT113, QT118H - QT411, QT511 We are committed to supporting customers currently using these products, but recommend using the QT100A or QT220 for any single/dual touch applications and the QT1106 for new touch slider or touch wheel designs. |
QTouch™ Chips
QTouch devices are digital charge-transfer ICs designed to detect touch using a single connection between the sensor chip and a simple key electrode. These chips are best suited for low key count applications up to 10 keys. More...
