摘要: ∑/△型ADC作为性能价格比优良的高精度AD转换器,在许多领域得到广泛应用.但由于自身模数转换机制的限制,它在多通道数据转换采集的应用中遇到了困难. 由此,引入流水线处理技术,实现了高效高转换率的多通道∑/△型ADC数据转换采集,并介绍了基于ADSP2106x的多通道高精度数据采集系统的应用实例.
关键词: 流水线&sum/△型ADC多通道数据采集    
Abstract: Sigma-delta type ADCs are applied widely in many region for its perfect performance.But it isn’t suitable for m ulti-channel multiplexed system lim ited by its conversation mechanism .Pipeline method is proposed to construct a high efficiency,high sam pling rate multi-channel data acquisition system ,and instance system based on ADSP2106x DSP is introduced.
Key words: pipe-line    sigma-delta ADC    multi channel data acquisition
