Description

AW83118G is a stereo efficient, Class-D audio power amplifier for driving speakers up to 60W/4Ω in PBTL mode. It can run 2×30W/8Ω without heat sink on a dual layer PCB. In Low-Loss mode, it consumes a low idle current, allowing for longer audio play and improved thermal performance in Speaker bar and Consumer Audio applications.

The AW83118G advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interferences; this is achieved together with an option of Master/Slave mode, making it possible to synchronize multiple devices.

The AW83118G built-in over-voltage, under-voltage protection, DC protection, thermal protection and short-circuit protection, effectively prevent it from being damaged.

AW83118G is available in ETSSOP 11mm×8.1mm- 32L package.
