A dual-slope analog to digital converter uses an N-bit counter. When the input signal V, is being integrated, the counter is allowed to count up to the value
The output voltage is related to the following equation: VA = k [2N-1 bN-1 + 2N-2 bN-2 + … 2b1 + b0] (Where k is a proportionality factor and bm are bits). This is an example of:
