方案描述：

The SGTL5000 is a low-power stereo codec that includes headphones and is designed to provide a comprehensive audio solution for portable products that require line-in, mic-in, line-out, headphone-out and digital I/O. It consumes less than 4 mw for DAC-to-HP out playback while achieving 98 dB SNR and -80 dB THD N. Deriving its architecture from best-in-class Freescale-integrated products currently on the market, the SGTL5000 is able to achieve ultra low-power with very high performance and functionality, all in one of the smallest footprints available. Designed with features such as capless headphone and an integrated PLL to allow clock reuse within the system, it helps customers achieve a lower overall system cost.
