AD5941 and CN0510 EIS Performance

Category: Datasheet/Specs
Product Number: AD5941

Hello team,

I am currently working with the AD5941 evaluation board and have encountered a few questions regarding its operation, particularly with the CN0510 Batz board:

1) When AFE us capable of frequency range from 0.01hz to 200khz. Why is CN0510batz board work correctly in the frequency range of 1hz to 5khz only and when i test it above 5k values it gives wrong output.

2) Please explain the excitation circuitry works, how values are measured and calculated.

3) Since this board uses potentiostatic method of EIS, please explain how the whole excitation and measurement mechanism works.

4) Why is AC amplitude is 300 by default, when in EIS is AC amplitude is supposed to be 10mV
