No question, no specifications... What do you expect? * Use the "simialar threads" in the box below * use the search function of this forum * use a internet serach engine **** * give specifications * Read some forum posts, articels, documents --> then ask a dedicated question Klaus

That will get you 200mV dc, but an opamp can increase that to 3.5v as required.
