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 applica-
tions. 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 8load.
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 gener-
ated when conventional solid state amplifiers are driven hard
into clipping.
The LME49810 includes thermal shutdown circuitry that ac-
tivates 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.
