摘要
介绍了16位Σ-ΔA/D转换器AD7705的基本特点以及滤波和校准功能,结合现场实际情况,详细介绍了现场校准和手动校准的步骤,并给出了手动校准实例。实验结果表明,AD7705的高精度数据采集得以实现。
The features as well as filtering and calibration functions of the 16-bit sigma-delta A/D converter AD7705 are introduced in this paper. It makes particular introduction on filed-calibration and manual-calibration according to the practical conditions in the filed, and an example about manual calibration is presented. As the results of experiment indicated, high-precision data acquisition of AD7705 is implemented.
