In the datasheet for the MAX15500, it says I need to use several diodes in series:
... to ensure a voltage difference of 2V to 3.5V from AVDD to AVDDO and from AVSS to AVSSO.
It seems to be that a 2V- 3.5V Zener diode should be able to replace all 5 of these diodes. If so, why are Maxim suggesting such an overly complicated circuit? Am I missing something?
