    Maximum driven shield electrode capacitance

    wtony_2694776

      Hi,

       

      I'm developing a linear slider on the CY8C4125LQI-483 with a driven shield. Just wondering if there is a maximum limit on the capacitance of the shield electrode before it stops being effective.

       

      Thanks,

          Hello,

           

          We recommend to add a Shield tank capacitor if the shield capacitance crosses 100pf.

          But we don't have an exact maximum value on the shield capacitance, having said that a value of 1nF should be good enough for the max shield capacitance.

           

          Also please note to add shield electrode across sensor for a max distance of 1cm.

           

          Thanks,
