I need to use the AD7266 because of the fast and simultaneous Sampling.
The Measurement needs to have Analog 5V but i communicate with Digital 3.3V over SPI.
In the Datasheet i saw "AVDD to DVDD −0.3 V to +0.3 V" ... does that mean it must be both 5V for AVDD and DVDD and only Vdrive needs to be 3.3V ?
or in other words: DVDD and VDrive does not have anything in common depending on "Digital Communication" ?
Thanks for the information
