Answer to Question #87766 in Electric Circuits for Sridhar

Question

A 12-bit counter type A/D converter used
a 1 MHz clock. Its maximum conversion
time is
(A) 1 μs
(B) 12 μs
(C) 4096 μs
(D) 4 μs

Answer 1

Maximum conversion time of a counter type ADC is

$$t=T2^n$$

where T - period of clock pulses, that for 1 MHz clock equals 1 microseconds;

n - number of bits.

So, maximum conversion time equals 4096 microseconds (C)
