QT1103 10-KEY SENSOR IC

lQ QT1103 QTOUCH™ 10-KEY SENSOR IC This datasheet is applicable to all revision 3 chips DETECT SYNC/LP VSS SNS7K SNS7 SNS6K SNS6 SNS5K The QT1103 is designed for low cost appliance, mobile, and consumer electronics applications. QTouch™ technology is a type of patented charge-transfer sensing method well known for its robust, stable, EMC-resistant characteristics. It is the only all-digital capacitive sensing technology in the market today. This technology has over a decade of applications e.

QT1103 Features

* as the older device but differs in the following ways:

* Rs resistors on each channel eliminated

* Up to 4x more sensitive for a given value of Cs

* Shorter burst lengths, less power for a given value of Cs

* ‘Burst A and B’ only mode for up to eight keys, with less p
