PAM8902A - MONO CLASS-D AUDIO AMPLIFIER

General Description

The PAM8902A is a mono, Class-D audio amplifier with integrated boost convertor designed for piezo and ceramic speakers.

The PAM8902A is capable for driving a ceramic/piezo speaker with 30VPP(0.6Vrms) from a 3.6V power supply.

Key Features

  • an integrated audio low pass filter that rejects high frequency noise, thus improving audio fidelity. PAM8902A also provides thermal, over current, under and over voltage protection. The PAM8902A is available in a 16-ball 1.95mm x 1.95mm CSP package and 16-pin QFN4x4 package. Pin Assignments Features.
  • Supply Voltage Range from 2.7V to 5.5V package.
  • 30VPP Output Load Voltage from a 2.7V Supply.
  • Integrated Boost Converter Generates 17.5V Supply.
  • Programmable.

A Product Line of Diodes Incorporated PAM8902A 30 VPP MONO CLASS-D AUDIO AMPLIFIER FOR PIEZO/CERAMIC SPEAKERS WITH ANTI-SATURATION Description The PAM8902A is a mono, Class-D audio amplifier with integrated boost convertor designed for piezo and ceramic speakers. The PAM8902A is capable for driving a ceramic/piezo speaker with 30VPP(0.6Vrms) from a 3.6V power supply. The PAM8902A'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 three gain mode of 18dB, 22dB and 26dB is easy for using. PAM unique ant i -saturat ion technology which detects output signal clip due to the over level input signal suppress the output signal clip automatically.
