LME49811
Audio Power Amplifier Series
November 11, 2009
High Fidelity 200 Volt Power Amplifier Input Stage with
Shutdown
General Description
The LME49811 is a high fidelity audio power amplifier input
stage designed for demanding consumer and pro-audio ap-
plications. Amplifier output power may be scaled by changing
the supply voltage and number of output devices. The
LME49811 is capable of driving an output stage to deliver in
excess of 500 watts single-ended into an 8 ohm load in the
presence of 10% high line headroom and 20% supply regu-
lation.
The LME49811 includes thermal shut down circuitry that ac-
tivates when the die temperature exceeds 150°C. The
LME49811's shutdown function when activated, forces the
LME49811 into shutdown state.
