FUNCT ION
DES CRIPT ION
The UTC
L4863
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, 4
load: 2.2W
-
HTSSOP-20, 3
load: 2.5W(with forced-air cooled)
-
SOP/DIP , 8
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.
