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
