DESCRIPTION

DIP-16 CMOS IC SOP-16 SOP-18 The UTC In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones. 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. HTSSOP-20 *Pb-free plating product number: L4863L
