Successive aproxmation

Question

how do you work out the conversion time and rate with a clock speed of 1MHz an analouge voltage of 4V to 4 bit binary and full scale DAC 5V

Answer 1

huh?

Answer 2

Successive Approximation ADCs use one clock cycle per bit, so at 1 MHz and 4 bits, it will take 4 µs total.
