DNL is the difference between an actual step width and
the ideal value of 1 LSB. A DNL error specification of
greater than -1 LSB guarantees no missing codes and
a monotonic transfer function.
Transition noise is the amount of noise that appears at a
code transition on the ADC transfer function. Conversions
performed with the analog input right at the code transi-
tion can result in code flickering in the LSBs.

Channel-to-channel isolation indicates how well each
analog input is isolated from the others. The channel-to-
channel isolation for these devices is measured by
applying a near full-scale magnitude 5kHz sine wave to
the selected analog input channel while applying an
equal magnitude sine wave of a different frequency to
all unselected channels. An FFT of the selected chan-
nel output is used to determine the ratio of the magni-
tudes of the signal applied to the unselected channels
and the 5kHz signal applied to the selected analog
input channel. This ratio is reported, in dB, as channel-
to-channel isolation.
