ADS52J90: Single-ended input drive with reduced performance?

Richard Raffanti

Part Number: ADS52J90

Hello,

I have an application requiring 320 channels of high-speed conversion; the ADS52J90 would be ideal. However my custom-ASIC preamplifier has only a single-ended output. Is it possible to drive the ADS52J90 inputs from a single-ended source, perhaps with reduced dynamic performance? 9-bit performance would likely be enough.

Thanks for any guidance.

Hi Rick,

Unfortunately, the ADS52J90 takes differential input signals only. One option is to use a balun to convert the single-ended signals to differential signals before connecting them to the ADS52J90.
There is another possible option but we'll have to take the discussion offline. Can you please provide your work email?

Sincerely,
Olu

Yes please:

was hoping to avoid 320 baluns also.

Thanks for your help
