LM4755 - Stereo 11W Audio Power Amplifier

General Description

The LM4755 is a stereo audio amplifier capable of delivering 11W per channel of continuous average output power to a 4Ω 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.
