LM4866 2.2W Stereo Audio Amplifier
General Description
The LM4866 is a bridge-connected (BTL) stereo audio power amplifier which, when connected to a 5V supply, delivers 2.2W to a 4 load (Note 1) or 2.5W to a 3 load (Note 2) with less than 1.0% THD+N.

With the LM4866 packaged in the LLP, the customer benefits include low thermal impedance, low profile, and small size. This package minimizes PCB area and maximizes output power. The LM4866 features an externally controlled, low-power consumption shutdown mode, and thermal shutdown protection. It also utilizes circuitry to reduce "clicks and pops" during device turn-on. Boomer audio power amplifiers are designed specifically to use few external components and provide high quality output power in a surface mount package.
