LTC1407A 具停机功能的串行、12 位、3Msps 同时采样 ADC
LTC®1407/LTC1407A 是具有两个 1.5Msps 同时采样差分输入的 12 位/14 位、3Msps ADC。这两款器件仅从单 3V 电源吸收 4.7mA 电流，并采用纤巧型 10 引脚 MS 封装。睡眠停机功能把功耗降至 10µW。速度、低功率和纤巧型封装的结合使 LTC1407/LTC1407A 成为高速、便携式应用的合适之选。
LTC1407/LTC1407A 具有两个单独的差分输入，它们在 CONV 信号的上升沿同时进行采样。两个输入采样后再以每通道 1.5Msps 的速率进行转换。
80dB 的共模抑制允许用户通过对信号源进行差分测量来消除接地环路和共模噪声。
这些器件可对 0V 至 2.5V 的单极输入进行差分转换。CH0+、CH0–、CH1+ 和 CH1– 的绝对电压摆幅从地扩展至电源电压。
串行接口利用 32 个时钟周期来发送两个转换结果，以实现与标准串行接口的兼容性。
