LME49810 200V Audio Power Amplifier Driver with Baker Clamp
General Description
The LME49810 is a high fidelity audio power amplifier driver designed for demanding consumer and pro-audio 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 300 watts into a single-ended 8 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 signals suppresses undesirable audio artifacts generated when conventional solid state amplifiers are 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
