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.
