SGTL5000: Ultra-Low-Power Audio Codec

Overview

The SGTL5000 is a low-power stereo codec designed to provide a comprehensive audio solution for portable products that require line-in, mic-in, line-out, headphone-out and digital I/O.

Featuring:

Ultra-low-power with very high performance and functionality
Capless headphone and an integrated PLL to allow clock reuse within the system that helps achieve a lower overall system cost.
