L4863
DUAL 2.2W AUDIO AMPLIFIER
PLUS STEREO HEADPHONE
FUNCTION
SOP-16
CMOS IC
SOP-18
DESCRIPTION
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, 4Ω load: 2.2W
- HTSSOP-20, 3Ω load: 2.5W(with forced-air cooled)
- 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.
