高精度多通道AD芯片ADS8364及其在有源电力滤波器中的应用

Application of High-accuracy ADS8364 in the Active Power Filter

ADS8364是美国TI公司的一款单5V供电的16位高速、低功耗、6通道同步采样模数转换器,主要应用于电机控制、多轴位置控制以及三相功率控制等场合。该文介绍了ADS8364的主要性能及特点,并以在基于现场可编程逻辑阵列(FPGA)的有源电力滤波器中的应用为例,介绍其具体应用方法和前端信号调理器的设计的关键点和技巧,并提供了采用FPGA状态机控制ADS8364的部分VHDL程序。

ADS8364 is a 250KSPS, 6-CH simultaneous sampling Analog-to-Digital converter with 16bit high-accuracy produced by TI Corporation. It’s designed for motor control, multi-axis positioning systems and 3-phase power control applications. This paper analyzes the major characteristics of this chip and presents its application in the Active Power Filter based on FPGA.
