QT112-S Description

The QT111 is a touch sensor IC having recalibration timeouts (“max on-duration”) of 5 minutes and infinity. Thisallows the device to be used in situations where recalibration timeouts are not desired, for example in certainconsumer, machine tool and process control applications where continuous touch over long periods is desired,like hand-on-joystick sensors, dead-man switches, etc. Although the primary application of the device is still as a‘touch sensor’, longer timeouts also aknowledge alternate uses for the QT110 family, for example in processcontrols.

QT112-S Description

The QT112 is a variant of the QT110 having a faster response time of 49ms worst case, and 25ms typical. It isdesigned for those touch sensing applications where faster speed is paramount, for example in games and toyswhere rapid reaction time is critical, or in machine tool controls where speed is important. It trades off powerconsumption for speed. Also, note that the device has a consensus filter count 2 instead of 4, and does not havean acoustic driver for a piezo 'beeper'.
