IAM-20680 accelerometer picks up EMI from nearby engine inverter

By wolfgangrappremescom , 30 September 2020

Hi,
I am using a IAM-20680 in a vehicle. As soon as an electric inverter for the e-engine is started, the accelerometer signals go mad.
The settings for the DLPF are
ACCEL_CONFIG +-16g
ACCEL_CONFIG2 0x05
Is this a known problem that the MEMS structure is sensitive for radiated electric / magnetic fields?
Have you got a recommendation for filtering?
Thanks
Wolfgang
