应用AD7741实现多路电化学生物传感器信号的隔离A/D采样设计

AD7741 based isolation A/D conversion for multi-electrochemical biosensor signals

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。

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.
