CS4384-CQZ集成电路（IC）的ADC/DAC-特殊用途规格书PDF中文资料

CS4384-CQZ属于集成电路（IC）的ADC/DAC-特殊用途。由凌云逻辑制造生产的CS4384-CQZADC/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 CS4384 is a complete 8-channel digital-to-analog system. This D/A system includes digital de-emphasis, half-dB step size volume control, ATAPI channel mixing, selectable fast and slow digital interpolation filters followed by an oversampled, multi-bit delta sigma modulator which includes mismatch shaping technology that eliminates distortion due to capacitor mismatch. Follow ing this stage is a multi-element switched capacitor stage and low-pass filter with single-ended analog outputs.

The CS4384 also has a proprietary DSD processor which allows for volume control and 50 kHz on-chip filtering without an intermediate decimation stage. It also offers an optional path for direct DSD conversion by directly using the multi-element switched capacitor array.
