QT115 - QUANTUM

QT115 QT 11x Series Variations

The QT111 is a touch sensor IC having recalibration timeouts (“max on-duration”) of 5 minutes and infinity. This allows the device 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 sens.

s with QT110 The QT111 sensor is exactly the same in all respects to the QT110 with the following exceptions shown in bold (refer to Table 2-1 in the QT110 datasheet): Table 2-1 Output Mode Strap Options Tie Pin 3 to: DC Out DC Out Toggle Pulse Vdd Vdd Gnd Gnd Tie Pin 4 to: Vdd Gnd Gnd Vdd Max OnDuration 300s infinite 300s 300s All other operating modes, specifications, and wiring should be read from the QT110 data sheet. QT111H Version The QT111H version is the same as the QT111 except has an active-high output. Cautionary Notes Care should be taken in infinite timeout mode that the Cs and.
