Product Summary

The LM4755T is a stereo audio amplifier capable of delivering 11W per channel of continuous average output power to a 8Ω load or 7W per channel into 8Ω using a single 24V supply at 10% THD+N. The internal mute circuit and pre-set gain resistors provide for a very economical design solution. The applications of the LM4755T are Stereos TVs, Compact stereos and Mini component stereos.
