ad5941 ocp measurement

Hi, How can ad5941 measure the open circuit potential(OCP) between RE and WE(or AINx) before EIS measurement?

  • Hi,

      If you want to measure just the open potential drop across the battery, in A5940BATZ, this drop is across AIN2 and AIN3 inputs.


    If so, you may configure ADC mux as below:

    dsp_cfg.ADCBaseCfg.ADCMuxN = ADCMUXN_AIN3;
    dsp_cfg.ADCBaseCfg.ADCMuxP =ADCMUXP_AIN2;

    This way, open circuit potential across the battery can be measured.
