LTC1403A 具停机功能的串行 14 位、2.8Msps 采样 ADC
LTC®1403/LTC1403A 是采用差分输入的 12 位/14 位、2.8Msps 串行 ADC。这些器件仅从单 3V 电源吸收 4.7mA 电流，并采用纤巧型 10 引脚 MS 封装。一种睡眠停机功能电路能够将功耗降低至 10μW。速度、低功率与纤巧型封装的组合使 LTC1403/LTC1403A 成为高速、便携式应用的合适之选。
80dB 的共模抑制使用户能够通过对来自信号源的信号进行差分测量以免除接地环路和共模噪声。
这些器件可对 0V 至 2.5V 的单双极输入进行差分转换。+AIN 和 -AIN 的绝对电压摆幅从地电位扩展至电源电压。
串行接口在 CONV↑ 之后的 16 个时钟周期中发送转换结果，以获得与标准串行接口的兼容性。如果在位于转换操作其间的数据流之后提供两个额外的时钟周期以用作采集时间，则在使用一个 50.4MHz 时钟的情况下能够实现 2.8Msps 的全采样速率。
