PAM8320

Overview
New Product Description The PAM8320 is an efficient 20W mono Class-D audio power amplifier, designed to drive speakers as low as 4Ω in a bridge-tiedload 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.
