Hi!, I apologize in advance for the stupid question. Friend mentioned the U3 to control a rotary element that should be fed with 0-8V to determine the rotational speed of the rotary element. I planed to use the VB sample code in order to set the voltages directly from the comuter. Is it true? do I need more than U3 to get 0-10V? Many thanks for your help Eli

The built-in DACs provide 0-5V output. To get 0-8V, you can use an op-amp or the LJTick-DAC:

How much current does your device need from the 0-8V signal? Can you provide a link to technical information about your rotary device, or any further details?
