PAM8902
30-VPP MONO CLASS-D AUDIO AMPLIFIER FOR PIEZO/CERAMIC SPEAKERS
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.
