DESCRIPTION

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. DIP-16 CMOS IC SOP-16 SOP-18 HTSSOP-20 *Pb-free plating product number: L4863L
