AT42QT1011

Electrode trace routing: Keep the electrode trace (and the electrode itself) away from other

signal, power, and ground traces including over or next to ground planes. Adjacent switching

signals can induce noise onto the sensing signal; any adjacent trace or ground plane next to, or

under, the electrode trace will cause an increase in Cx load and desensitize the device.

Important Note: for proper operation a 100 nF (0.1 µF) ceramic bypass capacitor must be

used directly between Vdd and Vss, to prevent latch-up if there are substantial Vdd

transients; for example, during an ESD event. The bypass capacitor should be placed

very close to the Vss and Vdd pins.

Power On

On initial power up, the QT1011 requires approximately 100 ms to power on to allow power

supplies to stabilize. During this time the OUT pin state is not valid and should be ignored.
