PAM8945 - Diodes

PAM8945 4.0W CLASS-G AUDIO AMPLIFIER

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 s.

Features

battery tracking AGC function which adjusts the amplifier gain to limit battery current at lower battery voltage. OUT- 3 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. Features
