PAM8902H

Description

The PAM8902H is a mono, Class-D audio amplifier with integrated boost converter designed for piezo and ceramic speakers. The PAM8902H is capable of driving a ceramic/piezo speaker with 30V_PP (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. And there are three gain modes of 21dB, 26dB, and 32.5dB for easy using. The PAM8902H also provides thermal, short, under and overvoltage protection.

The PAM8902H is available in a 16-ball 1.95mm x 1.95mm CSP-16L package and 16-pin W-QFN4040-16 (Standard) package.
