See the AN-835 Application Note, Understanding High Speed ADC Testing and Evaluation, for definitions and for details on how these tests were completed.
2
Measured on standard FR-4 material.
3
Can be adjusted via the SPI.
4
tSAMPLE/28 is based on the number of bits divided by 2 because the delays are based on half duty cycles. tSAMPLE = 1/fS.
5
Wake-up time is defined as the time required to return to normal operation from power-down mode.
