20W Mono Class D Audio Amplifier

Description

The PAM8320 is an efficient 20W mono Class-D audio power

amplifier, designed to drive speakers as low as 4Ω in a bridge-tied-

load configuration. Due to the low power dissipation and high

efficiency of up to 95%, the device can be used without any external

heat sink whilst playing music.

The PAM8320 features short circuit protection, thermal shutdown,

over voltage protection and under voltage lock-out.

The PAM8320 is available in a SO-16EP package.
