LME49830 - National Semiconductor

LME49830 Mono High Fidelity 200 Volt MOSFET Power Amplifier Input Stage

The LME49830 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 LME49830 is capable of driving an output stage in excess of 300 W single-ended into an 8Ω load in the presence of 10% high line head.
