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．
