Multichannel potentiostat circuit

Do you need to reverse the polarity of the cell voltage or will the current always flow in one direction? If one direction only, then the circuitry can be somewhat simple and only a single +5V supply will be required. You will not need a separate variable 2-3V supply as that voltage can be derived from the +5V and adjusted with a pot. If you have any of the NI voltage output modules it could be used to set the 2-3V and eliminate the manual pot. I can create a design using all through hole parts that you can build and prototype yourself. I will provide schematics and a BOM Please confirm the the maximum current is 5mA (milliamps) and not 5uA (microamps). Regards, Jim
