16位、单通道、超低功耗Σ-Δ型ADC

AD7788/AD7789均为适合低频测量应用的低功耗、低噪声、模拟前端。AD7789内置一个低噪声、24位∑-∆型模数转换器(ADC)，提供一个差分输入。AD7788是AD7789的16位版本。\n\n 该器件采用内部时钟工作。因此，用户不必为这些器件提供时钟源。输出数据速率为16.6 Hz，此时具有50 Hz/60 Hz同时抑制特性。\n\n 这些器件采用2.5 V至5.25 V单电源供电。采用3 V电源供电时，该器件最大功耗为225 µW。AD7788/AD7789采用10引脚MSOP封装。\n\n 智能发射器 电池应用 便携式仪器仪表 传感器 • 16位分辨率\n\n• 电源：\n• 工作电压：2.5 V至5.25 V\n\n• 正常模式：最大75 µA\n\n• 省电模式：最大1 µA\n\n\n\n\n• 均方根（RMS）噪声：1.5 µV\n\n• 16位峰－峰值分辨率\n\n• 积分非线性：3.5 ppm（典型值）\n\n• 50 Hz和60 Hz同时抑制\n\n• 内部时钟振荡器\n\n• VDD 监控通道\n\n• 10引脚MSOP封装;
