LM4950 7.5W Mono-BTL or 3.1W Stereo Audio Power Amplifier August 2004 LM4950 7.5W Mono-BTL or 3.1W Stereo Audio Power Amplifier General Description The LM4950 is a dual audio power amplifier primarily designed for demanding applications in flat panel monitors and TV’s. It is capable of delivering 3.1 watts per channel to a 4Ω single-ended load with less than 1% THD+N or 7.5 watts mono BTL to an 8Ω load, with less than 10% THD+N from a 12VDC power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4950 does not require bootstrap capacitors or snubber circuits. Therefore, it is ideally suited for display applications requiring high power and minimal size.
