... X7R type changes with temperature, the internal drift compensation mechanism also adjusts for the drift automatically. Piezo sounder drive: The QT110 can drive a piezo sounder after a detection for feedback. The piezo sounder replaces or augments the Cs capacitor; this works since piezo sounders are also capacitors, albeit with a large thermal drift coefficient ...

... S ENSITIVITY The QT110 can be set for one of 3 gain levels using option pin 5 (Table 1-1). If left open, the gain setting is high. The sensitivity change is made by altering the numerical threshold level required for a detection also a function of other ...

... However, the supply drain is so low simple matter to treat the entire controllable load; simply driving the QT110's Vdd pin directly from another logic gate or a microprocessor port (Figure 2-2) will serve as both power and 'forced recal'. The source resistance of most CMOS gates and microprocessors is low enough to provide direct power without any problems ...

... Out to ground (Figure 2-6). 2.2.6 O The QT110’s output is active low ; it can source 1mA or sink 5mA of non-inductive current. Care should be taken when the IC and the load are both powered from the same supply, and the supply is minimally regulated ...

... Detection ‘stiction’, the opposite effect, can occur if a load is shed when Out is active. The output of the QT110 can directly drive a resistively limited LED. The LED should be connected with its cathode to the output and its anode towards Vcc, so that it lights when the sensor is active-low ...

... Maximize Re to the limit where sensitivity is not affected not place the electrode or its connecting trace near other traces, or near a ground plane use a ground plane under and around the QT110 itself, back to the regulator and power connector (but not beyond the Cs capacitor). ...
