Responding to: ???'s previous message
I have worked out an Isolated 4-20mA receiver and transmitter.
I did send a lot of documentation, but it seems that I have lost contact, because I get no response.
I'm working on a board that takes care of interfacing the loop currents to your DAC/ADC board.
This board contains 2 receivers and 8 transmitters.
I had to use 1-5V intead of 0-5V but that is no problem for your controller (I hope).

Communication in this respect is very important, otherwise I'm talking to myself.
And you know time is very pressious to me, since I will leave for holiday within 5 days.

Tuesday I'm out of the office, but wednesday I'm stand by again.
If I do not hear of you by thursday, I assume that you are no longer interested in my help.

Sunday I will take off to California, I have send Mouser a mail for this very special FET I hope to pick it up in El Cajon (near San Diego)

In case I do not hear from you I wish you all the luck.
