SGTL5000, Low-Power Stereo CODEC with Headphone Amp - Fact Sheet

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.
