Product Summary
The LM4888SQ 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. It 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. The LM4888SQ features a low-power consumption shutdown mode and thermal shutdown protection. The LM4888SQ also utilizes circuitry to reduce clicks and pops during device turn-on.
