NXP Semiconductors SGTL5000 Low Power Stereo Codec

NXP SGTL5000 Low Power Stereo Codec comes with a Headphone Amp from Freescale. This Codec is designed to provide a complete audio solution for products needing LINEIN, MIC_IN, LINEOUT, and digital I/O. SGTL5000 is able to achieve low power with high performance in small footprints. This Codec has features such as capless headphone design and an internal PLL that helps lower the overall system cost.
