LM4755

Stereo 11W Audio Power Amplifier with Mute

General Description

The LM4755 is a stereo audio amplifier capable of delivering

11W per channel of continuous average output power to a

4

Ω 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.

Output power specifications at both 20V and 24V supplies

and low external component count offer high value to con-

sumer electronic manufacturers for stereo TV and compact

stereo applications. The LM4755 is specifically designed for

single supply operation.
