PAM8320RDR

PAM8320RDR is an efficient 20W mono Class-D audio power amplifier, designed to drive speakers as low as 4ohm 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. Applications include PC speaker, Bluetooth speakers, home sound systems, active speakers, and docking stations.

• Operates from 4.5V to 15V, 20W into 4ohm BTL load from 12V supply
