PAM8902H
Description
The PAM8902H is a mono, Class-D audio amplifier with integrated boost convertor 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 ponents. PAM8902H features an integrated audio low pass filter that rejects high frequency noise thus improving audio fidelity. And three gain modes of 21d B, 26d B and 32.5d B easy for using.PAM8902H also provides thermal ,short, under and over voltage protection.
The PAM8902H is available in a 16-ball 1.95mm x 1.95mm CSP package and 16-pin QFN4x4 package.
