PAM8902HKER is a mono, class-D audio amplifier with an integrated boost converter designed for piezo and ceramic speakers. The PAM8902H is capable of driving a ceramic/piezo speaker with 30VPP (10.6Vrms) from a 3.6V power supply. The PAM8902H's boost converter operates at a fixed frequency of 1.5MHz, and provides a 17.5V supply with a minimum number of external components. The PAM8902H features an integrated audio low-pass filter that rejects high-frequency noise, thus improving audio fidelity. The PAM8902H also provides thermal, short, under and overvoltage protection. Applications include wireless or cellular handsets, portable DVD players, personal digital assistants (PDAs), electronic dictionaries, and digital still cameras.
