General Description

The BL4863 is a dual BTL connected Class-AB audio power amplifier designed for multimedia monitors and other portable applications.

It is capable of delivering 2.5 watts of continuous average power to a 3Ω BTL load or 2.2 watts to a 4Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply.

In addition, the HP-IN input pin allows the BL4863 to operate in single-ended mode and drive stereo headphones.
