LM4880贴片8脚IC，5V双音频功放电路，无电容音响功放IC，舞台放大器
The LM4880 is a dual audio power amplifier capable of delivering typically 250mW per channel of continuous average power to an 8 load with 0.1% THD N using a 5V power supply.
Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging.
Since the LM4880 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.
The LM4880 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.
The unity-gain stable LM4880 can be configured by external gain-setting resistors.
