Differential Nonlinearity (DNL)

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

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

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.
