L4863 Datasheet | Unisonic Technologies

DESCRIPTION DIP-16 CMOS IC SOP-16 SOP-18 The UTC L4863 is a dual bridge-connected audio power amplifier. It bines 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.
