> I want to amplify voltage. It is a DAC output. Great, that narrows it right down to a few thousand choices. It would be best if you stated the overall problem. Little clues like what the output voltage range of the D/A is, what supply voltages are available, what will be done with the amplifier output signal, and what that signal's purpose is might help. If you keep supplying one tidbit at a time all the current chips will be obsolete before you will know what you want. ******************************************************************** Olin Lathrop, embedded systems consultant in Littleton Massachusetts (978) 742-9014, olin@embedinc.com, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
