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
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.
