Figure 1 shows a block diagram of the single slope, comparatorbased A/D converter. Using this approach an A/Dconverter can be configured by using only a single externalcapacitor. This capacitor provides the designer flexibility incontrolling the resolution and conversion time. visit page.
The externalcapacitor should be grounded on one side, and the positiveterminal should be reset to 0V by momentarily shorting thecapacitor through software control. An internal VCC/2 referencecan be used to calibrate the A/D conversion. For amore visit page.
