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.
