Description

The AW85180S is a mono, digital input Class-D audio amplifier optimized for efficiently driving high peak power into loudspeakers. The Class-D amplifier is capable of delivering 30W of continuous power into a 4Ω load with less than 1% THD+N at a supply voltage of 18V. The broad voltage input range and the high output power makes this amplifier versatile enough to work with battery or line powered systems. The AW85180S integrates SKTune algorithm that includes parametric audio path equalizer, dynamic range control, and smart protection, etc. The integrated speaker voltage and current sense provides for real-time monitoring of loudspeakers. PSM power architecture improves amplifier efficiency by internally selection the supplies for optimal headroom. Brownout prevention scheme with adjustable threshold allows reducing the gain in signal path when the supply drops. The PTC algorithm allows user to optimize efficiency and improve battery life by controlling the external power supply. Up to eight AW85180S devices can share a common bus via I2S/TDM and I2C interfaces. AW85180S is available in a 30 pin FCQFN 3.5mmX4mm-30L Package for a compact PCB footprint.
