Hey guys
I have a DC fan that works between 3 and 10 volts and needs 1A. I need to control it using a daq 6009 by varying the output voltage at the analog output of the daq. i am well aware that the daq cannot give the necessary current that the fan needs, so i need a power stage that isolates the daq and the fan so i dont damage the daq (which has only 5mA on its analog output)
can anyone give me some ideas of what should i use to give the current i need to use the fan? i heard about a current buffer but i have no idea about it
thanks!
