QT1080 - 8 KEY QTOUCH SENSOR IC

Features

  • which provide for reliable, trouble-free operation over the life of the product. Burst operation: The device operates in ‘burst mode’. Each key is acquired using a burst of charge-transfer sensing pulses whose count varies depending on the value of the reference capacitor Cs and the load capacitance Cx. In LP mode, the device sleeps in an ultra-low current state between bursts to conserve power. The keys’ signals are acquired using two successive bursts of pulses: Burst A: Keys 0, 1, 4, 5 Burst.
