LM4866 2.2W Stereo Audio Amplifier October 2002 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 4Ω load (Note 1) or 2.5W to a 3Ω 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.
