Abstract: We detailedly present a preamplifier circuit of an electrochemical biosensor,and an A/D conversion scheme of AD7741 based signal isolation.We eventually provide the program control flow for time sharing isolation A/D conversion of multichannel signals and correction method for A/D conversion data.
Key words: signal isolation, A/D conversion, AD7741
