I'm looking to hook up a piezoelectric PZT to a microcontroller that will be providing a white noise signal. However, the 5ish volts that the microcontroller can spit out isn't strong enough to vibrate the PZT as energetically as needed. Experiments have shown that a signal with 25 volts is the minimum needed (the PZT can handle voltages up to 300V) for the purpose.
The whole experiment is in a limited amount of space and (for now) run by several 9 volt long-life lithium batteries hooked up in parallel. Given those constraints on space and power, what is the best device, or at least the best category of devices for this job? If "nothing" is the answer, how best can I rearrange the batteries to provide for an alternative?
I don't mind having to assemble a few things together, but if the problem could be solved with one circuit or device, that would be ideal.
Thank you for your time and brain power. If I'm missing any vital details, I'll do my best to supply those upon request.
