ADC Driver for ADC3422

Guru 20090 points
Other Parts Discussed in Thread: ADC3422, THS4541

Hello,

Could you please let me know the recommended ADC Driver (Full Diff Amp.) and schematics for ADC3422?
Input signal is 10~50MHz(typ.25MHz), 1~2V.

I found that the Figure60 in the datasheet P.44.
However, the customer would like to use FDAamp for SE to Diff conversion and ADC driver.

Best Regards,

  • Hi Riyuji,

    Please have a look at this TIDA - it shows an active interface using the THS4541 FDA to provide an active buffered interface into the ADC3k family.  This would also be applicable to the ADC3422 as well.

    If you require any design assistance we can ask the amplifier team for help.  However I believe this TIDA would be a good reference point for the customer.
