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.
