Dear all,
this is the first time I post a thread. I hope I do it the proper way.
So here is my pb : I want to drive current into a coil so as to generate a magnetic field. This current should be quite strong (up to 5A) and I would like to drive it with various waveforms (square pulses or sinusoidal, up to 1kHz) provided by some external device (output board on a computer). It seems to me that I need a power transconductance circuit. But that's pretty much all I know because I'm not so good in electronics.
Could anyone give me a schematic on how to buid this, or a link to a webpage that describes how to build it and explains the ins and outs?
thanks in advance,
