Hi Matteo,
Oh yes, good catch - you are correct. I used the NSD value for the ADC3561 (-150 dBFS/Hz). Yes please substitute the -158 dBFS/Hz for the ADC3563 into the equation.
I did a search with these parameters on our device page. I had to back calculate…
Maitry,
The only part our group can offer is the ADC3561. Place this post on the Precision Data Converter forum for more possible options.
Regards,
Jim
