Description

AW8091 is an upgraded Class AB audio power amplifier that is compatible with AW8090 in pin definition and specifications;

AW8091 is a dedicated TDD rejection power amplifier with Thermal AGC, 1.26W (8Ω), Class AB audio; The patented Thermal AGC function can effectively protect the device from being damaged under overheating conditions, and avoid the phenomenon that traditional AB products play music intermittently under overheating conditions;

AW8091 has a built-in excellent Pop-Click noise suppression circuit to avoid Pop-Click noise during chip startup and shutdown operations;

AW8091 is capable of delivering 1.26W of continuous output power with typically 1% distortion (THD+N) when it drives an 8Ω speaker from a 5.0V power supply.

AW8091 is available in MSOP-8 package. It operates over an ambient temperature range of
-40°C to +85°C.
