低功耗、双通道、24位Σ-Δ型ADC

AD7787是一款适合低频测量应用的低功耗、完整模拟前端，内置一个低噪声24位Σ-Δ型ADC，该ADC具有一个差分输入和一个可缓冲或无缓冲的单端输入。\n\n 该器件采用内部时钟工作，因此，用户不必为其提供时钟源。AD7787的输出数据速率可通过软件编程设置，可在9.5 Hz至120 Hz的范围内变化，更新速率较低时均方根（RMS）噪声为1.1 µV。内部时钟频率可以使用系数2、4或8进行分频，从而可以降低功耗。更新速率、截止频率和建立时间与时钟频率成比例变化。\n\n 该器件采用2.5 V至5.25 V电源供电。工作电压为3 V时，最大功耗为225 µW，采用10引脚MS • 电源：\n- 工作电压：2.5 V至5.25 V\n- 正常模式：最大75 µA\n- 省电模式：最大1 µA\n\n• 均方根（RMS）噪声：1.1 µV（9.5 Hz更新速率时）\n\n• 19.5位峰－峰值分辨率（22位有效分辨率）\n\n• 积分非线性：3.5 ppm（典型值）\n\n• 50 Hz和60 Hz同时抑制;
