| The PAM8905 is a high efficiency Class-D audio power amplifier with an integrated boost converter. It drives up to 1.9W (1% THD+N) into an 8Ω speaker. With 85% typical efficiency, the PAM8905 helps extend battery life when playing audio. The built-in boost converter generates the voltage rail for the output stage. This provides a louder audio output than a stand-alone amplifier connected directly to the battery. It also maintains a consistent loudness, regardless of battery voltage. The PAM8905 features battery tracking AGC function which adjusts the Class-D gain to limit battery current at lower battery voltage. PAM8905 features DC input protection and all outputs are fully protected against output-to-output shorts. The PAM8905 is available in tiny WCSP12 (1.5mm x 2.0mm) packages. |
