GATE ECE - Digital circuits quetion

The resolution of an n bit DAC with a maximum input of 5 V is 5 mV. The value of n is [A]. 8 [B]. 9 [C]. 10 [D]. 11

Your Answer


Resolution = Analog Input/Number of Steps.

Number of Steps = (2^N)-1.

Resolution = 5 m.

Analog Input = 5.

N = 9.96 something.

In terms of resolution always round off to higher number. So 10 the simplified explanation
