QT112

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