(i.e., 0.008 × 0.5 = 0.004 V). Consequently, the relative accuracy reads a larger
ENOB than the absolute accuracy does.
Note that in the foregoing example, e
max
happens to have the same magnitude as
that of the offset error, which is the smallest possible output signal. Thus, Equation
(5.12) in a sense interprets the defi nition of dynamic range (DR), which is the ratio
of the largest possible to the smallest possible input/output signal values (here, it is
the ratio with respect to the output signal). Often, DR is expressed in decibels:
