Dual audio amplifier circuit using LM4940

Using LM4940 dual audio amplifier circuit can be designed a very simple low cost audio solution for demanding applications in flat panel monitors and TV’s, but it can be used for some other audio applications .

The LM4940 dual audio amplifier circuit does not require bootstrap capacitors or snubber circuits.
The LM4940 dual audio amplifier circuit is capable of delivering 6 watts per channel to a 4 ohms load with less than 10% THD+N while operating on a 14.4VDC power supply.
This audio amplifier circuit were designed specifically to provide high quality output power with a minimal amount of external components.
The audio amp ic features a low-power consumption active-low shutdown mode. Additionally, this audio amplifier ic features an internal thermal shutdown protection mechanism along with short circuit protection.
The audio amplifier contains advanced pop & click circuitry that eliminates noises which would otherwise occur during turn-on and turn-off transitions.
