DATASHEET
SGTL5000
Low Power Stereo Codec with Headphone Amp
DESCRIPTION
The Low Power Stereo Codec with Headphone Amp from
Freescale is designed to provide a complete audio solution
for portable products needing line-in, mic-in, line-out,
headphone-out, and digital I/O. Deriving it’s architecture
from best in class Freescale integrated products that are
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 portable media players, GPS units and
smart phones. Features such as capless headphone design
and an internal PLL help lower overall system cost.
