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 depending on desired function. 15. The voltage is expressed in peak-to-peak differential swing. The peak-to-peak singled-ended swing is 1/2 of the differential swing. 16. The relative propagation delay is the timing of the output clock of any A/D with respect to the nominal timing of any other A/D, given that all devices are clocked at the same time and are matched in temperature and voltage. It is specified over the full operating temperature and voltage range, and is established by characterization and not production tested. 17. The pipeline latency of this converter is fixed. 18. SPI Interface timing is directly proportional to the A/D sample period (tSAMPLE). 19. The SPI may operate asynchronously with respect to the A/D sample clock. 20. 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 time (4ns min). |
