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

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.

Output power specifications at both 20V and 24V supplies

and low external component count offer high value to consumer

electronic manufacturers for stereo TV and compact

stereo applications. The LM4755 is specifically designed for

single supply operation.
