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
4
load or 7W per channel into 8 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 con-
sumer electronic manufacturers for stereo TV and compact
stereo applications. The LM4755 is specifically designed for
single supply operation.
