AD7799 and  AD420 on same SPI

Hello

 

om my board There is one ad7799 and ad420 .

after setup ad7799 I realized that unlike ad7799 the ad420 need clock

to be low in ideal state .

 

is there any solution for this problem ?

 

and as i see in ad420 it accept all data in Data in and just after rise edge apply data .

is there probably any problem that on same spi there is another communication .

is it guarantee that just the last word before latch is applied ?

 

 

Best Regards
