DUAL 2.2W AUDIO AMPLIFIER

PLUS STEREO HEADPHONE

FUNCTION

CMOS IC

 DESCRIPTION

The UTC LM4863 is a dual bridge-connected audio power

amplifier. It combines dual bridge speaker amplifiers and stereo

headphone amplifiers on one chip to simplify audio system design.

In addition, the headphone input pin allows the amplifiers to

operate in single-ended mode when driving stereo headphones.

The IC could deliver different power by packages as below (when

connected to a 5V supply with less than 1.0% THD+N.):

- HTSSOP-20, 4Ω load: 2.2W

- HTSSOP-20, 3Ω load: 2.5W(with forced-air cooled)

- SOP/DIP , 8Ω load: 1.1W.

The UTC LM4863 features an externally 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.

 FEATURES

* “Click and pop” suppression circuitry

* Thermal shutdown protection circuitry

* Unity-gain stable

* Stereo headphone amplifier mode
