PAM8905 Product details

Description

Pin Assignments 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.12 3 A PVDD SW BGND 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, reg

Features

battery tracking AGC function which adjusts the Class-D gain to limit battery current at lower battery voltage. B OUT+ AGC VBAT C OUT- EN IN+ D PGND AGND IN- (TOP VIEW) PAM8905 features DC input protection and all outputs are fully protected against output-to-output shorts. The PAM8905 is available in U-WLB1520-12 package. Features.
