CS5372A集成电路（IC）的ADC/DAC-特殊用途规格书PDF中文资料

CS5372A属于集成电路（IC）的ADC/DAC-特殊用途。由凌云逻辑制造生产的CS5372AADC/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 CS5371A and CS5372A are one- and two-channel, high-dynamic-range, fourth-order ΔΣ modulators intended for geophysical and sonar applications. When combined with CS3301A / CS3302A differential amplifiers, the CS4373A test DAC and CS5376A digital filter, a small, low-power, self-testing, high-accuracy, multichannel measurement system results.
