MS1808 是带有采样速率 8kHz ~ 96kHz 的立体声 A/D 转换器，适合于面向消费者的专业音频系统。
MS1808 通过使用增强型双位  技术来实现其高精度的特点。MS1808 是单端的模拟输入所以不需要外部器件。音频接口有两种类型(最高有效位对齐， I 2S )适合用于像 DTV,DVR 和 AV 接收器的系统。

The CS8406 is a monolithic CMOS device which encodes and transmits audio data according to the AES3,IEC60958, S/PDIF, o r EIAJ CP1201 standards. The
CS8406 accepts audio and digital data, which is thenmultiplexed, encoded, and driven onto a cable.
The audio data is input through a configurable, 3-wireinput port. The channel status and user bit data are input through an SPI™ or I2C® microcontroller port, and
may be assembled in block-sized buffers. For systemswith no microcontroller, a Stand-Alone Mode allows direct access to channel status and user bit data pins.
The CS8406 is available in a 28-pin TSSOP and SOICpackage for both Co mmercial (-10o to +70oC) andAutomotive grade (-40o to +85oC). The CDB8416Demonstration board is also available for deviceevaluation and implementation suggestions. Please
refer to “Ordering Information” on page 34 for completedetails.
Target applications include A/V Receivers, CD-R, DVD
receivers, digital mixin g consoles, effects processors,
set-top boxes, and computer and automotive audio systems.
