DESCRIPTION

The UTC L4863 is a dual bridge-connected audio power

DIP-16

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

HTSSOP-20, 4Ω load: 2.2W

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

*Pb-free plating product number: L4863L

SOP/DIP

, 8Ω load: 1.1W.

The UTC L4863 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

* Thermal shutdown protection

* Unity-gain stable

* Stereo headphone amplifier mode
