com SNAS006E – FEBRUARY 1999 – REVISED APRIL 2013 LM4752 Stereo 11W Audio Power Amplifier Check for Samples: LM4752 FEATURES 1 •2 Drives 4Ω and 8Ω Loads • Internal Gain Resistors (AV = 34 dB) • Minimum External Component Requirement • Single Supply Operation • Internal Current Limiting • Internal Thermal Protection • Compact 7-lead TO-220 Package • Low Cost-Per-Watt • Wide Supply Range 9V - 40V APPLICATIONS • Compact Stereos • Stereo TVs • Mini Component Stereos • Multimedia Speakers DESCRIPTION The LM4752 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 LM4752 is specifically designed for single supply operation and a low external component count.
The gain and bias resistors are integrated on chip, resulting in a 11W stereo amplifier in a compact 7 pin TO-220 package.
High output power levels at both 20V and 24V supplies and low external component count offer high value for compact stereo and TV applications.
A simple mute function can be implemented with the addition of a few external components.
