LM4919
Description
The unity gain stable LM4919 is both a mono-BTL audio power amplifier and a Single Ended (SE) stereo headphone amplifier. Operating on a single 1.5V supply, the mono BTL mode delivers 85m W into an 8Ω load at 1% THD+N. In Single Ended stereo headphone mode, the amplifier delivers 14m W per channel into a 16Ω load at 1% THD+N. With the LM4919 packaged in the MM package, the customer benefits include low profile and small size. This package minimizes PCB area and maximizes output power. The LM4919 features circuitry that reduces output transients ("clicks" and "pops") during device turn-on and turn-off, an externally controlled, low-power consumption, active-low shutdown mode, and thermal shutdown. Boomer audio power amplifiers are designed specifically to use few external ponents and provide high quality output power in a surface mount package.
