See the AN-835 Application Note, Understanding High Speed ADC Testing and Evaluation, for a complete set of definitions and how these tests were completed.
2
This can be adjusted via the SPI interface.
3
Measurements were made using a part soldered to FR4 material.
4
tSAMPLE/24 is based on the number of bits divided by 2 because the delays are based on half duty cycles.
