The LME49811 is a high fidelity audio power amplifier input stage designed for demanding consumer and pro-audio applications. 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 regulation.
The LME49811 includes thermal shut down circuitry that activates when the die temperature exceeds 150°C. The LME49811's shutdown function when activated, forces the LME49811 into shutdown state.
