LM4888 - Dual 2.1W Audio Amplifier Plus Stereo Headphone

Description

The LM4888 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W to a 4Ω load (Note 1) or 2.4W to a 3Ω load (Note 2) with less than 1.0% THD+N.

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

Features

  • a low-power consumption shutdown mode and thermal shutdown protection. It also utilizes circuitry to reduce “clicks and pops” during device turn-on. Note 1: An LM4888SQ that has been properly mounted to a circuit board will deliver 2.1W into 4Ω. See the.

A user selectable “National 3D Enhancement” mode provides enhanced stereo imaging. The LM4888SQ 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.
