Audio CODECs SGTL5000 Low-power stereo codec with headphone amp Overview Freescale’s SGTL5000 is a low-power stereo codec that includes a headphone amp and is designed to provide a comprehensive audio solution for products that require LINEIN, MIC_IN, LINEOUT, headphone output and digital I/O. Deriving its architecture from the 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. Target markets include media players, navigation devices, smartphones, tablets, medical equipment, exercise equipment, consumer audio equipment, etc. Designed with features such as capless headphone and an integrated PLL to allow clock reuse within the system, Freescale helps customers achieve a lower overall system cost.
