LM4752
Stereo 11W Audio Power Amplifier
General Description
The LM4752 is a stereo audio amplifier capable of delivering
11W per channel of continuous average output power to a
4
load, or 7W per channel into 8 using a single 24V supply
at 10% THD+N.
The LM4752 is specifically designed for single supply opera-
tion 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 TO220 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.
