MPXV5010DP under electric field problem

AEb2 — Tue, 03 Feb 2026 21:30:08 GMT

Hi,

I have MPXV5010DP assembled on board.

During electric field 50V/m, at several frequencies, projected on it ( from distance of 1 meter), the sensor started to output failed analog signals ( it should be 0).

Do you know about this type of phenomena? any suggestion how to eliminate it?

Thanks

Hello Aharon,

Strong electric fields can induce unwanted noise or disturbances in sensitive analog circuits, resulting in erroneous sensor outputs.

Here are some suggestions to mitigate this effect:

Surround the sensor and associated circuitry with a conductive enclosure or shield. Make sure the shield is properly grounded to prevent electric fields from penetrating and affecting the sensor.

Ensure that the sensor and the surrounding electronics have a good ground connection. Keep the signal traces as short as possible. Use ground planes to provide shielding and better grounding.

Place decoupling capacitors near the power supply pins of the sensor to stabilize the power and reduce noise sensitivity.

Unfortunately it is difficult to diagnose without more data, but I believe that implementing some of these suggestions can help mitigate the effects of EMI and stabilize the sensor output under electric field exposure.

BRs, Tomas
