产品概述
The LM4809 is a dual audio power amplifier capable of delivering 105mW per channel of
continuous average power into a 16Ω load with 0.1% (THD+N) from a 5V power supply.Boomer audio power amplifiers were designed specifically to provide high quality output
power with a minimal amount of external components. Since the LM4809 does not require bootstrap
capacitors or snubber networks, it is optimally suited for low-power portable systems.The unity-gain stable LM4809 can be configured by external gain-setting resistors.The LM4809 features an externally controlled, active-low, micropower consumption shutdown
mode, as well as an internal thermal shutdown protection mechanism.
