LM4980 2 节电池、1mA、42mW/通道高保真立体声耳机音频放大器 - MP3 播放器

The LM4980 is a stereo headphone audio amplifier, which when connected to a 3.0V supply, delivers 42mW to a 16 load with less than 1% THD+N. With the LM4980 packaged in the SD package, the customer benefits include low profile and small size. This package minimizes PCB area and maximizes output power.

The LM4980 features circuitry that significantly reduces output transients ("clicks" and "pops") while driving headphones during device turn-on and turn-off without costly external additional circuitry. The LM4980 also includes an externally controlled low-power consumption active-low shutdown mode, and thermal shutdown. Boomer audio power amplifiers are designed specifically to use few external components and provide high quality output power in a surface mount package
