The PAM8906 is a piezoelectric sounder driver with built-in boost converter, capable of driving a piezo sounder with up to 36VPPoutput. With integrated boost converter, the PAM8906 can provide an optimized solution with higher Sound Pressure Level (SPL) for louder output sound, and lower quiescent current along with auto turn-on/off feature for extended battery runtime. PAM8906 provides clear benefits for battery-operated piezoelectric sounder or alarm related applications.
