Sonitron New Piezo Audio Amplifiers
The Piezo Audio Amplifiers series are a total solution to drive piezoceramic sound components. A range of different PCB sizes, amplifier topologies and maximum voltage peak to peak outputs, cover a wide solution to piezo audio amplification. Piezo audio amplifiers are designed to handle capacitive loads and have the possibility to deliver large voltages peak to peak over the complete audio frequency range. The PAA-series give a quality amplifier where a quality sound is needed.
