Texas Instruments  LM4752TS/NOPB

The LM4752 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 LM4752 is specifically designed for single supply operation and a low external component count. The gain and bias resistors are integrated on chip, resulting in a 11W stereo amplifier in a compact 7 pin TO-220 package. High output power levels at both 20V and 24V supplies and low external component count offer high value for compact stereo and TV applications. A simple mute function can be implemented with the addition of a few external components.
