LN4088

Dual 2.7W Stereo Audio Amplifier Plus Headphone Driver LN4088 ■ General Description ■ Features The LN4088 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.7W to a 4Ω load. To simplify audio system design, the LN4088 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip. The LN4088 features a low-power consumption shutdown mode and thermal shutdown protection. It also utilizes circuitry to reduce “clicks and pops” during device turn-on. ■ Key Specifications  Power Output @1% THD+N & VDD=5V LN4088 RL=4Ω 2.2W (TYP) RL=8Ω 1.4W (TYP)  Power Output @10% THD+N & VDD=5V LN4088 RL=4Ω 2.7W (TYP) RL=8Ω 1.7W (TYP)  Power Output @1% THD+N & VDD=4V LN4088 RL=4Ω 1.4W (TYP) RL=8Ω  Shutdown current 0.88W (TYP) 0.04uA(TYP.)  Supply voltage 2.0V~5.5V  Stereo headphone amplifier mode  “Click and pop” suppression circuitry  Unity-gain stable  Th...
