    I want to know how long it takes for the AD5941 to scan EIS from 0.015hz to 200khz

  • AD5941 Sequencer Optimisation


    We are developing a product with the AD5941 which requires accurate and flexible synchronisation between high speed DAC and ADC sampling.

    We have successfully developed an application using sequences controlled via the wake-up timer. This approach…

  • AD5941 Real and Imaginary Impedance

    Hi there,

    I would like to know the best approach to have available in my MCU the real and imaginary parts of the measured impedance.

    After studying the examples available on GitHub I understand that a calibration resistor/value is used to obtain the value…

  • AD5941 min Vpp, when output sine wave.

    AD5941 can output sine wave, the min vpp can set low to 10mV or not?

    If can set to 10mV, how to set the register? 


  • RE: AD5941 impedance

    Yes. Gain calibration must be done.

  • Parallel SPI communication while measuring on AD5941

    We are trying to get a very fast impedance measurement on the Ad5941, with the EVAL-AD5941ELCZ evaluation kit. We will need an impedance output at approximately 1000 Hz. The excitation frequency can unfortunately not be very large, it should be around…

  • AD5941 EIS 6 cell battery measurement


    Apologies if this seems a dumb question. Can I used the AD5840/5941 to perform Electrochemical Impedance Spectroscopy on a battery of cells?

    I want to test a 6 cell lithium battery, as a minimum across the battery of 6 cells, ideally use more devices…

  • RE: AD5941: PCB layout

    Dear Igor,

    Thank you for your reply. I wrote, I am (only) a chemical engineer and teacher. So I haven't had enough practice to design potentiostat with
    AD5941. Therefore I ask you to help me. I designed a very simple potentiostat, with a quad amplifier…
