com SNAS010E – FEBRUARY 1999 – REVISED APRIL 2013 LM4755 Stereo 11W Audio Power Amplifier with Mute Check for Samples: LM4755 FEATURES 1 •2 Drives 4Ω and 8Ω Loads • Integrated Mute Function • Internal Gain Resistors • Minimal External Components Needed • Single Supply Operation • Internal Current Limiting and Thermal Protection • Compact 9-lead TO-220 Package • Wide Supply Range 9V - 40V APPLICATIONS • Stereos TVs • Compact Stereos • Mini Component Stereos 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.
