ESD Protection AD7747

Hello at all,


i make measurements in a powder conveyer where we have electrostatic discharge with more than 15kV,

which is killing the ad7747's signal-generator and CAP-inputs.


Inside the tank we use a sensor with three different isolated electrodes on potentials CIN+, CIN- and EXC.

I search for an esd protection circuit for the ad7747 inputs/outputs CIN+, CIN- and EXC.


Hope, that anyone knows a solution which is not influencing the measurement.
