General Description

The LM4752 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 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 TO220 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.

Features

  • Drives 4 and 8 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

Key Specification

  • Output power at 10% THD+N with 1kHz into 4 at VCC = 24V: 11W (typ)
  • Output power at 10% THD+N with 1kHz into 8 at VCC = 24V: 7W (typ)
  • Closed loop gain: 34dB (typ)
  • PO at 10% THD+N @ 1 kHz into 4 single-ended TO-263 package at VCC = 12V: 2.5W (typ)
  • PO at 10% THD+N @ 1kHz into 8 bridged TO-263 package at VCC = 12V: 5W (typ)

Applications

  • Compact stereos
  • Stereo TVs
  • Mini component stereos
  • Multimedia speakers
