6通道、低噪声、低功耗、24位Σ-Δ型ADC，内置片内仪表放大器和基准电压源

AD7794/AD7795均为适合高精度测量应用的低功耗、低噪声、完整模拟前端，内置一个低噪声24位/16位Σ-Δ型ADC，其中含有6个差分输入，还集成了片内低噪声仪表放大器，因而可直接输入小信号。\n\n 每款器件均内置一个精密低噪声、低漂移内部带隙基准电压源，也可采用最多两个外部差分基准电压。其它片内特性包括可编程激励电流源、熔断电流控制和偏置电压产生器，利用偏置电压产生器可将某一通道的共模电压设置为AVDD/2。低端电源开关可用来在两次转换之间关断桥式传感器，从而使系统功耗降至较低。AD7794/AD7795可以采用内部时钟或外部时钟工作，输出数据速率可在4.17 Hz至470 • 最高23位有效分辨率\n\n• 均方根（RMS）噪声：40 nV（4.17 Hz时），85 nV（16.7 Hz时）\n\n• 功耗：400 µA（典型值）\n\n• 省电模式：最大1 µA\n\n• 低噪声可编程增益仪表放大器;
