If resolution of a D/A converter is approximately 0.4% of its full-scale range. then it is a/an

1. 8 – bit converter
2. 10 – bit converter
3. 12 – bit converter
4. 16 – bit converter

Correct Option: A

As =	1	≤ 0.004
	2^N - 1

∴ 2^N > 251
⇒ N = 8,
hence minimum value of N satisfying the condition.
