Specification Definitions
APERTURE JITTER is the variation in aperture delay from
sample to sample. Aperture jitter shows up as input noise.
APERTURE DELAY is the time from the sampling edge of
the clock to when the input signal is acquired or held for con-
version. In other words, it is the time required for the Sample/
Hold circuit to go from the sample mode to the hold

mode. The Sample/Hold circuit effectively stops capturing
the input signal and goes into the hold mode this amount of
time after the clock transition.
DIFFERENTIAL NON-LINEARITY (DNL) is the measure of
the maximum deviation from the ideal step size of 1 LSB.
EFFECTIVE NUMBER OF BITS (ENOB, or EFFECTIVE
BITS) is another method of specifying Signal-to-Noise and
