Hello,

does someone have schematics of 100w power amplifier for 25-30 kHz range?
I need to run piezzo speaker, with impedance like 0,3 uF ( from datasheet)

I calculate that this is around 20 ohms at 25 kHz ( hope it is correct) 🙂

For input I will make 25kHz squre wave signal.

thank you in advance
Joe
