ADR421 and ADP7104ARDZ-50 schematics and PCB files (Altium Designer)

Hi everyone,

I'm presently designing a new Board with the simultaneous sampling A/D converters AD7606-8. Thanks to Analog Devices, I have AD7606 schematic and PCB file, but I'm missing me some devices for my design project (working with Altium Designer).

Please could you help to find the schematics and PCB files for the ADR421 and ADP7104ARDZ-50 devices ? I don't find them...

Thank you very much!
