DESCRIPTION

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.
