1. Is there any requirements for the power sequencing of ADS8405 since there are two power supplies (VA and VDB) ? I can't find any information about that in the datasheet.
2. Can I place capacitors on REFOUT pin even if I use an external Vref connected to REFIN or should I remove them (dual-version board with options)?
Hello Christophe
There is no need to place capacitors on REFOUT if using an external reference, REFOUT can be left unconnected. If you would like, you can place an unpopulated 0ohm resisitor between pin REFOUT and REFIN to have the option available to use the internal reference. You will also need to disconnect the external reference device if using the internal reference.
