CS4397-KS集成电路（IC）的ADC/DAC-特殊用途规格书PDF中文资料

CS4397-KS属于集成电路（IC）的ADC/DAC-特殊用途。由凌云逻辑制造生产的CS4397-KSADC/DAC - 特殊用途该产品族中的产品可用于模拟和数字表示的信息转换，适用于特定用例，或集成了通用数据转换器中不常见的其他功能。例如针对超声或汽车雷达应用集成了低噪声放大器和可变增益级的器件、注重音频和视频的产品、在段码式显示器上集成显示测量值功能的器件、集成输入输出电气隔离的器件等。

描述 Description

The CS4397 is a complete high performance 24-bit 48/96/192 kHz stereo digital-to-analog conversion system. The device includes a digital interpolation filter followed by a oversampled multi-bit delta-sigma modulator which drives dynamic-element-matching (DEM) selection logic. The output from the DEM block controls the input to a multi-element switched capacitor DAC/lowpass filter, with fully-differential outputs. This multi-bit architecture features significantly lower out-of-band noise and jitter sensitivity than traditional 1-bit designs, and the advanced DEM guarantees low noise and distortion at all signal levels.
