NATIONAL SEMICONDUCTOR LM4940 6W Stereo Audio Power Amplifier handbook

Update: 30 September, 2023

The LM4940 is a 6W stereo audio power amplifier primarily designed for demanding applications in flat panel monitors and TVs. It is capable of delivering 6 watts per channel to a 4Ω load with less than 10% THD+N while operating on a 14.4VDC power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4940 does not require boot-strap capacitors or snubber circuits. Therefore, it is ideally suited for display applications requiring high power and mini- mal size. The LM4940 features a low-power consumption active-low shutdown mode. Additionally, the LM4940 features an inter- nal thermal shutdown protection mechanism along with short circuit protection. The LM4940 contains advanced pop & click circuitry that eliminates noises which would otherwise occur during turn-on and turn-off transitions. The LM4940 is a unity-gain stable and can be configured by external gain-setting resistors.
