Title: Designing ADC frontend?
Post by gct on Apr 21^st, 2008, 9:30pm

OK, so I'm traditionally a digital guy, but I thought I'd give some RF design a shot, so I'm jumping in trying to design an RF frontend for an ADC chip, specifially the LTC2209 by linear. The ADC has a 700MHz bandwidth, and I'd like to leave that as open as possible since the goal with this whole thing is to produce a frontend suitable for general purpose acquisition. The frontend needs to convert a single-ended input to a double-ended input to drive the chip, other than that requirements aren't any different than for any general ADC frontend. Right now I'm soliciting comments/suggestions/tips/examples that people think might be useful to me as I move forward on this. I imagine this will be painful because I've never enjoyed analog, but wish me luck!

What do you want to know ?

If your first target's ADC is LTC2209 of LTI, you should begin with studying specifcations and characteristics of LTC6600-20 and LTC1993 of LTI.

Driver amplifiers of ADI and TI are also great helpful in studying design specifications for ADC frontend.
