摘　　要：详细介绍德国IC-Haus公司生产的13位Sin/D转换器IC-NQ的性能特点、引脚功能、工作原理、数据输出接口、应用设置。结合光栅读数头和精密运算放大电路,通过对该器件的编程设定细分数,实现了光栅位移测量系统,并将其应用于粗糙度测量仪中。试验结果表明,该器件运行稳定,性能可靠,可有效提高光栅位移测量系统的位移分辨率,达到位移的0.1μm的细分,为设计高精度粗糙度仪提供参考。The features, pin description,operation principle, data output interface and configuration of 13-bit SirdD converter IC-NQ which is developed by IC-Haus Company are introduced detailedly in the paper. Combining optical reading head and precise amplifier circuit, the optical grating displacement system was realized by programming to set up subdivided parameter value. The system was used in surface roughness tester. The experimental result shows that the chip has high stability and reliability and the displacement resolution is improved effectively. The 0.1μm of subdivided displacement is obtained, which provides a foundation to realize a surface roughness tester with high precision.
