Product Summary
The LM4873MTE 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 to drive stereo headphones. A Mux Control pin toggles between the two stereo sets of amplifier inputs, allowing for two selectable amplifier closed-loop responses.
