Product Summary

The QT411-ISSG QSlide IC is a new type of linear capacitive touch slider sensor IC based on Quantum’s patented charge-transfer (‘QT’) methods. The QT411-ISSG allows designers to create speed or volume controls, menu bars, and other more exotic forms of human interface on the panel of an appliance or personal electronic device. Generally it can be used to replace any form of linear control, through a completely sealed panel.

Parametrics

QT411-ISSG absolute maximum ratings: (1)Operating temperature range, Ta: -40℃ to +85℃; (2)Storage temperature range, Ts: -55℃ to +125℃; (3)VDD: -0.5 to +7.0V; (4)Max continuous pin current, any control or drive pin: ±20mA; (5)Short circuit duration to ground, any pin: infinite; (6)Short circuit duration to VDD, any pin: infinite; (7)Voltage forced onto any pin: -0.6V to (Vdd + 0.6) Volts; (8)VDD: +2.5 to 5.0V; (9)Supply ripple+noise: 5mV p-p max; (10)Cs1, Cs2, Cs3: 100nF; (11)Cs1, Cs2, Cs3 relative matching: ±5%; (12)Output load, max: ±0.5mA.
