In the following circuit, the comparator output is logic “I” if V1 > V2 and is logic “0” otherwise. The D/A conversion is done as per the relation
$$${V_{DAC}} = \sum\limits_{n = 0}^3 {{2^{n - 1}}{b_n}\,\,} Volts,$$$
where b3(MSB), b2, b1 and b0 (LSB) are the counter outputs.
The counter starts from the clear state.
The stable reading of the LED display is
