I am working on a bioimpedance application and have been using the AD5940 eval kit. In one of the application notes, it ahs the following.
I have been looking through the 60601 standard as it relates to this application and I cannot find a reference for where the max allowable ac current as a function of frequency is stated. Does anybody know where the values in the application note come from. I admittedly get very easily lost in reading the standard, but the closest thing I could find are the references to Patient Auxiliary Currents, which appear to be limited to 100uA in normal operation and are not frequency dependent.
Any steer in the right directions would be appreciated.
