QT111

The QT111 is a touch sensor IC having recalibration timeouts ("max on-duration") of 5 minutes and infinity. This allows the QT111 to be used in situations where recalibration timeouts are not desired, for example in certain consumer, 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 QT111 is still as a 'touch sensor', longer timeouts also aknowledge alternate uses for the QT110 family, for example in process controls.
