LM4883 Dual 2.1W Audio Amplifier Plus Stereo Headphone Function November 2004 LM4883 Dual 2.1W Audio Amplifier Plus Stereo Headphone Function General Description The LM4883 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W to a 4Ω load (Note 1) or 2.4W to a 3Ω load (Note 2) with less than 1.0% THD+N. In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones. A MUX control pin allows selection between the two stereo sets of amplifier inputs. The MUX control can also be used to select two different closedloop responses.
