流水线技术实现高效多通道∑/Δ型ADC数据采集系统

Using pipeline technique to realize high efficiency multi-channel sigma-delta type ADC data acquisition system

Σ/Δ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Σ/Δ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.

Sigma\|delta type ADCs are applied widely in many region for its perfect performance. But it isn't suitable for multi\|channel multiplexed system limited by its conversation mechanism. Pipeline method is proposed to construct a high efficiency, high sampling rate multi\|channel data acquisition system, and instance system based on ADSP2106x DSP is introduced.
