Texas Instruments ADC16DX370 双通道 16 位模数转换器
德州仪器 ADC16DX370 双通道 16 位模数转换器是一款单片双通道高性能模数转换器,能够以 370MSPS 的采样速率将模拟输入信号转换为 16 位数字字。这款转换器采用差分流水线架构,并集成了输入缓冲器,在提供优异动态性能的同时,保持着较低功耗。该集成式输入缓冲器消除了来自内部开关电容器采样电路的电荷回馈噪声,并且简化了驱动放大器、抗混叠滤波器以及阻抗匹配的系统级设计。一个输入采样时钟分频器凭借可配置相位选择提供整数分频比,以简化系统计时。集成低噪声电压基准在无需外部去耦合电容器的情况下简化了电路板级设计。在 56 引脚,8mm x 8mm WQFN 封装中,通过一个 JESD204B 1 子类接口提供输出数字数据。可使用 SPI 来配置与 1.2V 至 3.0V 逻辑电路兼容的器件。特性
