Henry,
someone will look into this. Could you please advise SFDB specification and defintion? I am only aware of SFDR (spurious free dynamic range). Perhaps you had a typo?

Hi Henry,

Please see below link for introduction to DAC basics. It includes SFDR definition.

Since the DAC38RF80 is a wideband DAC, there are additional SFDR parameters that limits the BW for more practical applications (i.e. In band SFDR)
