LN4888 - Dual 2.1W Audio Amplifier Plus Stereo Headphone & 3D Enhancement

General Description

The LN4888 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W to a 4Ω load or 2.4W to a 3Ω load with less than 1.0% THD+N.

A user selectable “3D Enhancement” mode provides enhanced stereo imaging.

LN4888 Dual 2.1W Audio Amplifier Plus Stereo Headphone & 3D Enhancement ■ General Description The LN4888 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W to a 4Ω load or 2.4W to a 3Ω load with less than 1.0% THD+N. A user selectable “3D Enhancement” mode provides enhanced stereo imaging. The LN4888 also has two separate HP (headphone) enable inputs, each having different logic level thresholds. Either HP enable input activates the single ended headphone mode and disables the BTL output mode. The HP Sense input is for use with a normal stereo headphone jack. The remaining input, HP Logic, accepts standard logic level thresholds.
