integrated headphone amplifier. It 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 USB clocking mode (12 MHz SYS_MCLK input)
help lower overall system cost.
