Description

The PAM8902 is a mono, Class-D audio amplifier with integrated boost converter designed for piezo and ceramic speakers.The PAM8902 is capable of driving a ceramic/piezo speaker with 30VPP(10.6Vrms) from a 3.6V power supply.The PAM8902's Boost converter operates at a fixed frequency of 1.5MHz, and provides a 17.5V supply with a minimum number of external components. PAM8902 features an integrated audio low pass filter that rejects high frequency noise thus improving audio fidelity. And three gain modes of 18dB, 22dB and 26dB for ease of use. PAM8902 also provides thermal, short, under- and over-voltage protection. The PAM8902 is available in a 16-ball 1.95mm x 1.95mm CSP package and 16-pin QFN4x4 package.
