一种基于ADS5232的高速数据采集电路的设计方法
A Design Method of High Speed Data Acquisition Circuit Based on ADS5232
摘要
Abstract
A practical high speed data acquisition circuit was designed based on high-speed ADC chip ADS5232 . Among this circuit, two sampling channels were integrated into ADS5232, and the chip did not need to provide external reference voltage, and therefore it can simplify PCB design. Two channels use the same clock, so that the synchronous sampling can be realized. The highest sampling rate of each channel reaches 65 MS/s and the accuracy is 12 bit. The data acquisition circuit consists of three parts including ADC front end, ADS5232 and FPGA, which support single-end signal and difference signal analog inputs, FPGA is used to realize high speed control and to design the interface with external application circuit for connection and the RAM on chip is configurated as data buffer. This circuit can realize high speed AD, control, cache and interface with external logic.关键词
