ADS8528, ADS8548 and ADS8568 timing concerns
The ADS85x8 operates from 5-V analogue core (AVdd) for the conversion process, it uses high voltage rails (HVdd and HVss) of up to ±12V for the input stage, and features a digital input/output buffer rail (DVdd) of 2.7 to 5.5 V for interfacing to a variety of processors.
There are eight independent data converters within the package that operate in channel pairs – A0/1, B0/1, C0/1 and D0/1. The conversion process for each channel pair is controlled by applying the associated convert start input.
