Introduction

AI Translation

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. The PAM8945 features DC input protection and all outputs are fully protected against output- to- output shorts. The PAM8945 is available in tiny W- QFN2030- 12 package.
