ADC12DS080: Comparison of ADC12DS080 and ADC3222

Hi Koki,

1.  Yes, both terms are the same. 

2.  What is your desired frequency?

3. looking into it

The actual desired frequency has not been decided.
I would like to know because the frequency characteristics (frequency-dec) are not written in the data sheet.
Please tell us about the following two.
・ Frequency where ADC3222 attenuated by 5db
・ Frequency where ADC12DS080 attenuated by 5db

Thanks,

Hi Koki,

We do not recommend going outside the 3db range for either device. For ADC12DS080, any AC signal that is less than or equal to 1Ghz will work. For the ADC3222, DC or AC signal can be used up to 540Mhz

I'm sorry.

I made a mistake. I would like to know the following frequencies.

・ Frequency where ADC3222 attenuated by 0.5db

・ Frequency where ADC12DS080 attenuated by 0.5db

Thanks,

Hi, Miguel

Do you have any update?

Thanks,

Hi Koki,

I'm working on collecting the data.

Hi Koki,

I will share data for ADC3222 by on of day today. Still working on ADC12DS080.

Hi Koki,

I didn't have a board where it was a straight connection to the input of the device. Performance will be better by ~.2db since

there was loss due to the transformers. this is the plot for ADC3222. 

Hi Koki,

unfortunately, we don't have a ADC12DS080. If you tell me your desired frequency and Fs clock I'd be more than happy to suggest another part
