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.

Features

  • Drives 4 and 8 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

Key Specification

  • Output power at 10% THD with 1kHz into 4 at VCC = 24V: 11W (typ)
  • Output power at 10% THD with 1kHz into 8 at VCC = 24V: 7W (typ)
  • Closed loop gain: 34dB (typ)
  • PO at 10% THD+N @ 1kHz 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

  • Stereos TVs
  • Compact stereos
  • Mini component stereos
