I need to amplify a square wave that is driving a piezo disk at 100 Hz (or less). I'm limited by the output of my function generator to 10 V. I need 50 or even 100 V. What is a cheap way of amplifying the output of my signal generator that will preserve the square wave at 100 Hz? Will an audio amplifier work? They are intended to drive low impedence loads (for instance 8 ohm). How will that work with a high impedence load (my piezo disk)?
My budget is $50 or less. OK, $100 or less max.
Thanks for your help.
