Any old instrumentation amp may not be what you need,
some ADCs want really stiff drivers to tamp down kickback
noise and such. More a high speed thing as I make it out,
but I'd take ADC mfrs' hints about well mated front ends.
DC CM vs HF CM is another point to ponder. Fewer options
if you're really after high frequency (conducted susceptibility
testing or whatever).
