The PAM8902ZER-P is a mono, Class-D audio amplifier designed specifically for driving piezo and ceramic speakers. It operates from a supply voltage range of 2.5V to 5.5V and can deliver an output load voltage of 30VPP (10.6Vrms) from a 3.6V power supply. The integrated boost converter generates a 17.5V supply at a fixed frequency of 1.5MHz, requiring minimal external components. This amplifier features selectable gain settings of 18dB, 22dB, and 26dB, along with an integrated audio low pass filter to enhance audio fidelity by rejecting high-frequency noise. It also includes built-in protections for thermal, short circuit, under-voltage, and over-voltage conditions, ensuring reliable operation. The PAM8902 is available in compact packages, specifically a 16-ball 1.95mm x 1.95mm CSP package and a 16-pin QFN4x4 package, making it suitable for space-constrained applications such as wireless handsets, portable DVD players, and digital cameras. However, it is noted that this part is not recommended for new designs, with the PAM8902H suggested as an alternative.
