Hello all.
I am trying to make a simple amplifier Circuit, and I just can't get it right.
Here is what I'm trying to do:
I have a program on my laptop that can generate signals (sine waves, squire waves, noise etc). I would like to connect the output from my laptop (speaker out - Jack stick) to a Circuit, which has a 24v power supply, and boost the signal from the laptop in such way, that the amplitude of the output is 24v or close to that. Also the amp should be able to handle squire waves, sine waves etc.
I've modeled many Circuits (Class AB amplifiers and similar) on LT Spice, but it seems that the output amplitude never dives below 0v and always stays above. I've also though about using opto amps like the 4580, but a simple transistor Circuit just seems better, or am I wrong?
Basically if I have a +/- 3v output amplitude from my laptop, I would like to feed the signal to an amp, that generates a +/- 24v amplitude of the same signal. Also should I use special components if the output signal frequency is 20KHz or above?
Many thanks in advance.
