Touch Keys ≤10

QTouch™ Chips

IMPORTANT NOTE

The QT100, QT110, QT113, and QT118H products are no longer recommended for new designs.

We are committed to supporting customers currently using these products, but recommend using the QT100A or QT220 for any single/dual touch designs.

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...
