... The QT switches and charge measurement hardware functions are all internal to the QT113 (Figure 1-2). A 14-bit single-slope switched capacitor ADC includes both the required QT charge and transfer switches in a configuration that provides direct ADC conversion. The ADC is designed to ...

... S ENSITIVITY The QT113 can be set for one of 2 gain levels using option pin 5 (Table 1-1). This sensitivity change is made by altering the internal numerical threshold level required for a detection. Note that sensitivity is also a function of other things: like the ...

... Decreasing Sensitivity In some cases the QT113 may be too sensitive, even on low gain. In this case gain can be lowered further by a number of strategies: making the electrode smaller, making the ...

... OPT1 and OPT2. All options are shown in Table 2-1. 2.2 The output of the QT113 can respond mode, where the output is active-low upon detection. The output will remain active-low for the duration of the detection, or until the Max On-Duration expires (if not infinite), whichever occurs first ...

... O D UTPUT RIVE The QT113’s `output is active low and can sink up to 5mA of non-inductive current inductive load is used, such as a small relay, the load should be diode clamped to prevent damage. When set to operate in a proximity mode (at high gain) the current should be limited to 1mA to prevent gain ...
