Switching Specifications
NOTES:
10. SPI Interface timing is directly proportional to the ADC sample period (4ns at 250Msps).
12. The CSB setup time increases in sleep mode due to the reduced power state, CSB setup time in Nap mode is equal to normal mode CSB setup
11. The SPI may operate asynchronously with respect to the ADC sample clock.

8. The Tri-Level Inputs internal switching thresholds are approximately 0.43V and 1.34V. It is advised to float the inputs, tie to ground or AVDD
9. The input clock to output clock delay is a function of sample rate, using the output clock to latch the data simplifies data capture for most
