Specification Definitions
ANALOG INPUT BANDWIDTH is a measure of the fre-
quency at which the reconstructed output fundamental drops
3 dB below its low frequency value for a full scale input. The
test is performed with f
tiples of f
−3 dB relative to the low frequency input signal is the full
power bandwidth.
DIFFERENTIAL GAIN ERROR is the percentage difference
between the output amplitudes of a high frequency recon-
structed sine wave at two different dc input levels.
DIFFERENTIAL NON-LINEARITY (DNL) is the measure of
the maximum deviation from the ideal step size of 1 LSB.

DIFFERENTIAL PHASE ERROR is the difference in the out-
put phase of a reconstructed small signal sine wave at two
different dc input levels.
EFFECTIVE NUMBER OF BITS (ENOB, or EFFECTIVE
BITS) is another method of specifying Signal-to-Noise and
Distortion Ratio, or SINAD. ENOB is defined as (SINAD -
1.76)/6.02 and says that the converter is equivalent to a per-
fect ADC of this (ENOB) number of bits.
FULL POWER BANDWIDTH is a measure of the frequency
at which the reconstructed output fundamental drops 3 dB
below its low frequency value for a full scale input. The test
is performed with f
