31VPP OUTPUT PIEZO SOUNDER DRIVER WITH BOOST CONVERTER
Pin Assignments
The PAM8907 is a piezoelectric horn driver with built-in boost converter, capable of driving a ceramic/piezo sounder with up to 31VPP output. With integrated boost converter, the PAM8907 can provide an optimized solution with higher Sound Pressure Level (SPL) for louder output sound, lower quiescent current for longer standby time, and auto turn-on/off feature for extended operating lifetime. The PAM8907 provides clear benefits for battery-operated tracker, piezoelectric horn or alarm related applications.
The PAM8907 integrates a boost converter that operates at a typical frequency of 1.8MHz. With...
