Hi all,
I'd like to amplify a 1 volt peak to peak, 30 Hz sine wave I'm generating using a National Instruments USB adapter into a 24 volt signal for use with a fairly powerful electromagnet (it draws about 0.8 amps when hooked up to 24 VDC).
Is there an amplifier that will allow me to pass enough current to make this work? I tried talking to the folks at TI, but they weren't very helpful. Also, is there protection circuitry that I'll need to have to keep the back EMF from the electromagnet from damaging the rest of the system?
Any help would be very appreciated. Thanks.
