ETK4888 - Dual bridge-connected audio power amplifier

General Description

The ETK4888 is a dual bridge­connected 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.

The ETK4888 also has two separate HP (headphone) enable inputs, each having different logic level thresholds.

Key Features

  • Stereo headphone amplifier mode Selectable 3D Enhancement 2.2~5.5v operation voltage Micro power shutdown mode Improved “click and pop” suppression circuitry Thermal shutdown protection circuitry Unity­gain stable Package: QFN24 (ETK4888Y).

General Description The ETK4888 is a dual bridge­connected 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. The ETK4888 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. Features Stereo headphone amplifier mode Selectable 3D Enhancement 2.2~5.
