## Description

The LM4755T is a stereo audio power amplifier designed for single supply operation, offering significant value for consumer electronics manufacturers. It can deliver 11W per channel of continuous average output power to a 4Ω load or 7W per channel into an 8Ω load when using a single 24V supply at 10% THD+N.

Key features include an integrated mute circuit and pre-set gain resistors, which contribute to a very economical design solution with minimal external components. The amplifier is designed for wide supply voltage operation, ranging from 9V to 40V, and includes internal current limiting and thermal protection for enhanced reliability.

Applications for the LM4755T include stereo televisions, compact stereo systems, and mini component stereos. It is available in a compact 9-lead TO-220 package and a TO-263 package, supporting surface mount applications.

Electrical characteristics include a typical closed-loop gain of 34dB. The device operates efficiently with a quiescent current of 7mA (typical) when muted and up to 15mA (maximum) when unmuted. Total harmonic distortion is typically 0.08% at 1W/ch into 8Ω.
