AD7714在温度测量中的使用要点

On the Application of AD7714 in Temperature Measure

AD7714是一种低噪声高精度Δ-Σ模数转换器,适用于低频测量应用的完整模拟前端,可以直接接在传感器上,简化系统设计,降低整体成本。应用中需要重点注意内部缓冲器、数字滤波器、校准模式三个方面的使用,能大幅度提高测量精度。

The AD7714 is a △-E analog-to-digital converter of low noise and high accuracy, applicable to low frequency analogue front interface, and can be connected directly to sensors, simplifying the system design and lowering the cost. In the application of the AD7714,it needs to be paid attention to the uses of the internal buffer, digital filter, calibrating mode, which can significantly improve the measure accuracy.
