Etek Microelectronics ETK4888
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.
