Hi.) In datasheet was described ad1556 work with ad1555 that have a 1-bit out stream. Also is written possibility to work with another del.sig modulator but about ad1556 input resolution is written nothing. Please tell me, can i join a mash sig.delt modulator with 2-bit out with ad1556? Thanks) sorry for my english))
