【摘要】 应用AD7741设计了一款电化学生物传感器的前置电路,给出了多路前置用AD7741进行信号隔离的A/D采样方案,提供了对多路信号进行分时隔离A/D采样的程序控制流程和对A/D采样数据的校正处理方法。更多还原

【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 multi-channel signals and correction method for A / D conversion data.更多还原
