LM4888 Datasheet (National Semiconductor) - Dual 2.1W Audio Amplifier Plus Stereo Headphone

LM4888, Dual 2.1W Audio Amplifier Plus Stereo Headphone

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.

The LM4888SQ also has

LM4888 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 Application Information sections for further i
