SGM4888 Dual 2.1W Audio Power Amplifier Plus Stereo Headphone & 3D Enhancement
GENERAL DESCRIPTION
The SGM4888 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W into a 4Ω load or 2.5W into a 3Ω load with typically 1% THD+N.
The SGM4888 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.
To simplify audio system design, the SGM4888 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.
