Driver ICs for piezo-electric speakers

15 November 2006 Analogue, Mixed Signal, LSI

Recently, National Semiconductor released two piezo-electric speaker driver ICs for piezoceramic speaker applications. Sonitron, a leading European manufacturer of piezo-ceramic audible components, says that in combination with only a few external components, these audio power amplifier ICs are an excellent solution to drive its SPS piezo-ceramic speakers.

The specs of the LM4960SQ device can be found at www.national.com/pf/LM/LM4960.html and that of the LM4961LQ at www.national.com/pf/LM/LM4961.html. For test results with Sonitron's standard piezo ceramic speaker models, see www.sonitron.be/Media/Measurement_Report_LM4960_&_LM4961.pdf.
