Hello list.

I need to get A/D + DSP + D/A for 4/20 mA signals.
I wonder if any of you knows good sources for optocoupled 4-20mA 
receivers/transmitters ICs doing the job. I will do DSP. :) Also non 
monolithic will do, but I am rather looking for a not space hungry solution.

Many thanks in advance.

Alessandro
