LM4863

UNISONIC TECHNOLOGIES CO., LTD LM4863 DUAL 2.2W AUDIO AMPLIFIER PLUS STEREO HEADPHONE FUNCTION CMOS IC  DESCRIPTION The UTC LM4863 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 LM4863 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.  FEATURES * “Click and pop” suppression circuitry * Thermal shutdown protection circuitry * Unity-gain stable * Stereo headphone amplifier mode  ORDERING INFORMATION Ordering Number Lead Free Halogen Free LM4863L-D16-T LM4863G-D16-T - LM4863G-S18-R - LM4863G-N20-R Package DIP-16 SOP-18 HTSSOP-20 Packing Tube Tape Reel Tape Reel www.unisonic.com.tw Copyright © 2016 Unisonic Technologies Co., Ltd 1 of 12 QW-R107-027.E LM4863  MARKING Packing DIP-16 SOP-18 HTSSOP-20 MARKING CMOS IC UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 12 QW-R107-027.E LM4863  PIN CONFIGURATION DIP-16 ...
