Regarding suitability of AD9257BCPZ-40 as an alternative based on max DNL

Category: Datasheet/Specs
Product Number: AD9257BCPZ40, AD9257, AD9257


The old design had ADC part (single channel, parallel output part) AD9245BCPZ-20 which has maximum DNL of +/- 1 LSB.

The chosen alternative ADC part (octal channel, serial LVDS) AD9257BCPZ-40 has maximum DNL of 1.7 LSB.

How much of the performance difference will this extra 0.7 LSB of DNL makes?
