This signal is compared with the voltage divided by resistors and digitized. This digitized signal is coded by the encoder logic and output on the next rising edge of the CLK input signal. The conversion range depends on the converter high and low reference voltage VRH and VRL. When zero transient voltage is set to 3.000 V by VRL voltage and full scale transient voltage to 4.984 V by VRH voltage, the output data is linearly related to the input voltage as shown in the table below. 0 1 2 3 .. ..
