AD7124-8 SPI level shift using ADG3300

Hello,

we need to interface the AD7124-8 with an ATMEGA32U4 (5V mcu) through SPI. We are conisdering the attached shifting diagram:

Does anybody have any insight on:

1. Will we have any issues with the fact that we are not using any pull-ups particularly to the CS pin? (I think the ADG3300 pins will not be able to handle lowervalue pull-ups - like less than 50k)

2. Is there a recommended buffer we should use to overcome the pull-up issue?

3. Is there an alternate arrangement we should consider?

Thanks in advance!

-Steve
