The LME49810TB is a high fidelity Audio Power Amplifier Driver designed for powered subwoofers and powered studio monitors applications. Amplifier output power may be scaled by changing the supply voltage and number of power transistors. The LME49810"s minimum output current is 50mA. When using a discrete output stage the LME49810 is capable of delivering in excess of 300W into a single-ended 8R load. Unique to the LME49810 is an internal baker clamp. This clamp insures that the amplifier output does not saturate when over driven. The resultant soft clipping of high level audio signal suppresses undesirable audio artifacts generated when conventional solid state amplifier is driven hard into clipping. The LME49810 includes thermal shutdown circuitry that activates when the die temperature exceeds 150°C. The LME49810"s mute function, when activated, mutes the input drive signal and forces the amplifier output to a quiescent state.
