200V audio power amplifier eliminates more than 25 discrete components

National Semiconductor Corporation has introduced an addition to its family of 200V power amplifier output stage drivers. The LME49810 is a single-chip 200V driver with integrated Baker Clamp that replaces more than 25 discrete components in high-power audio amplifiers. The LME49810 joins the LM4702 stereo driver as the newest member of National’s high-performance audio family.

The LME49810 contains all the essential audio circuitry required for a high-quality, high-performance power amplifier output stage driver. The single-chip device saves space and design time by replacing a myriad of discrete components -- many of which must be hand selected and matched by the audio system designer. The LME49810 not only reduces system cost and simplifies design, but it also enables slimmer, more elegant designs, with more channels and more power per square-inch of chassis space.

The LME49810 is optimal for high-end consumer and professional audio applications that span powered studio monitors and subwoofers, audio/visual (AV) receivers, commercial sound reinforcement, after-market audio, professional mixers, distributed audio and guitar amplifiers.
