Charge redistribution to achieve A/D conversion. In typical applications, as a ratiometric conversion system for a microprocessor,VREF- will be connected to ground and VREF,+will be connected to VCC. The output will then be a simple proportional ratio between analog input voltage and VCC. The general relationship is: Where DOUT=Digital Output VIN=Analog Input VREF=Positive Reference Potential VREF= Negative Reference Potential
