Description:

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

Applications

* " 100% autocal for life - no adjustments required " Direct outputs - either encoded or ‘per key’ " Fully debounced results " 2.8V to 5.0V single supply operation " 45µA current typ @ 3V in 360ms LP mode " AKS™ Adjacent Key Suppression " Spread spectrum bursts for superior noise rejection OSC VDD SNS
