PAM8945 4.0W CLASS-G AUDIO AMPLIFIER WITH INTEGRATED BOOST CONVERTER AND BATTERY TRACKING AGC PROVISIONAL PRODUCT Description Pin Assignments (Top View) The PAM8945 is a high-efficiency Class-G audio power amplifier with an integrated boost converter. It drives up to 4.0W (10% THD+N) into a 4Ω speaker. With 85% typical efficiency, the PAM8945 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 PAM8945 features battery tracking AGC function which adjusts the amplifier gain to limit battery current at lower battery voltage.
