Hello, I need to design a current amplifier. I'm trying to design a virtual instrument in LabVIEW to which I can type in a current (for example 1.5 Amps) and then have that current realized at the output of a current amplifier. I believe LabVIEW will provide a small voltage which I can feed into the current amplifier and then use the output of that.
I'm going to be using this to drive a real small load of only 15 Ohms. and would like to be able to push 2 Amps through it (this would be my maximum current). I think I will be driving the amplifier wtih millivolts from that DAQ. So I guess this would be the same as having a 30 Volt output?
This is the first time I've ever attempted to design an amlifier and was wondering if anyone could give me a little guidance or point me in the right direction. I think what I'm trying to make is a: voltage controlled current amplifier. I was wondering
1) Where should I be looking for something like this, at Op-Amps, FETs, BJTs? 2) Whats the difference between a current amplifier and a voltage amplifier, in this case it seems like you could describe this as either.appreciate any help i could get with this thanks joshua
