Configuration programming of a digital audio serial port using no additional pins

摘要

A stereo digital-to-analog converter is able to operate in an 8 pin package yet to operate under a variety of serial data input formats. The normal de-emphasis pin can be used for receiving a static de-emphasis signal, an external serial clock, or programming data for the serial data formats. In addition metal and wire bond options are used to provide more flexibility in the manufacturing process.
