Piezo Audio Amplifier - 600nF, 24Vpp, Class AB (25x25 mm) - All SPS Series

Speakers are used in a wide range of applications going from small portable devices to complete
audio systems. Today’s market is mainly dominated by electromagnetic speakers which have a
voice coil and a heavy permanent magnet. Portable devices however require small, light speakers
which are also energy efficient in order to increase battery life. Piezoceramic speakers are the
perfect solution for such applications. In this upcoming market Sonitron has developed the flat
piezoceramic SPS-speakers which are based on a new composite membrane that ensures an even
frequency response.
To drive these piezo speakers Sonitron also has developed a complete range of piezo audio
amplifiers to increase the audio voltage. The sound pressure level generated by a piezospeaker is in
direct relation with the audio voltage which is applied. Therefore the amplifier needs to be chosen
carefully.
