The LM4867 is a dual-channel bridge-connected audio power amplifier that will deliver 2.1W 4 when connected to a 5V power supply 3 loads or 2.4W THD+N less than 1.0% load The LM4867 features advanced, latest generation circuitry to eliminate all traces of clicks and persistent organic pollutants when the supply voltage is first applied. The amplifier has an input pin for the headphone amplifier of your choice. It is an amplifier used to switch on and off, from the bridge to the driving headset in single-ended mode. A new circuit topology eliminates the headphone output coupling capacitance (patent pending). The MUX control pin allows for a choice between two sets of stereo input signals. MUX control, which can also be used to select two different customer-specified closed-loop reactions.

Boomer audio power amplifiers are designed to provide high-quality output power in a surface-mount package and require few external components. To simplify audio system design, the LM4867 combines a dual-bridge speaker amplifier and a stereo headphone amplifier in a single package.

The LM4867 features externally controlled power-saving micropower shutdown mode, a stereo headphone amplifier mode, and thermal shutdown protection.
