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.
