Dual 2.1W Audio Amplifier Plus Stereo Headphone Function

The LM4883 is a dual bridge-connected Audio Power Amplifier which, when connected to a 5V supply, will deliver 2.1W to a 4 load or 2.4W to a 3 load 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 closed-loop responses.
Boomer Audio Power Amplifiers were designed specifically to provide high quality output power from a surface mount package while requiring few external components. To simplify Audio system design, the LM4883SQ combines dual bridge speaker Amplifiers and stereo Headphone Amplifiers on one chip.
The LM4883SQ features an internally controlled, low-power consumption shutdown mode, a stereo Headphone Amplifier mode, and thermal shutdown protection. It also utilizes circuitry to reduce "clicks and pops" during device turn-on.
