3v. This should result in an output code of 117 (decimal) or 75 (hex). The SAR register sets the MSB, making the internal DAC voltage 2.5v. Since the signal is below 2.5v, the SAR resets bit 7 and sets bit 6 on the next clock. The ADC “chases” the input signal, Digital-to-Analog Converters 27 ending up with a final result of 12710 (7F16). The actual voltage at the end of the conversion is 2.8v, corresponding to a code of 14310 (8F16). The final code out of the ADC (127d) corresponds to a voltage of 2.48V. This is neither the starting voltage (2.3v) nor the ending voltage (2.8v). This example used a relatively fast input to show the effect; a slowly changing input has the same effect, but the error will be smaller. One way to reduce these errors is to place a low-pass filter ahead of the ADC. The filter parameters are selected to insure that the ADC input does not change appreciably within a conversion cycle.
