LM4810中文资料具有数字音量控制和关断模式的 105mW 立体声、模拟输入耳机放大器数据手册TI规格书

描述 Description

The LM4810 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 LM4810 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The unity-gain stable LM4810 can be configured by external gain-setting resistors. The LM4810 features an externally controlled, active-high, micropower consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.
