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 consumer electronic manufacturers for stereo TV and compact stereo applications. The LM4755 is
specifically designed for single supply operation.
