LM4868 Datasheet (National Semiconductor) - Dual 2.1W Audio Amplifier

LM4868, Dual 2.1W Audio Amplifier

The LM4868 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.

The LM4868 uses advanced, latest generation circuitry to eliminate all traces of clicks and pops when the

LM4868 Features

* an externally controlled power-saving micropower shutdown mode, a stereo headphone amplifier mode, and thermal shutdown protection. Note 1: An LM4868LQ or LM4868MTE that has been properly mounted to a circuit board will deliver 2.1W into 4Ω. The Mux control can also be used to select two different c
