Find the conversion time of a Successive Approximation A/D converter which uses a 2 MHz clock and a 5-bit binary ladder containing 8V reference. What is the Conversion Rate?
Ans. As give frequency of the clock (F) = 2 MHZand Number of bits (n) = 5
(i) Conversion Time (T) = n/clock rate = 5/(2 x 106) = 2.5 µ sec
(ii) Conversion Rate = 1/T = 1/(2.5x 106) = 400,000 conversion/sec.
