The LME49830 is a high fidelity audio power amplifier inputstage designed for demanding consumer and pro-audio applications.Amplifier output power may be scaled by changingthe supply voltage and number of output devices. TheLME49830 is capable of driving an output stage in excess of300 W single-ended into an 8Ω load in the presence of 10%high line headroom and 20% supply regulation.The LME49830 includes internal thermal shut down circuitrythat activates when the LME49830 die temperature exceeds150°C. The LME49830 has a mute function that mutes theinput drive signal and forces the amplifier output to a quiescentstate.
