Accelerometer resonance frequency

george — Tue, 03 Feb 2026 20:55:55 GMT

Dear All,

My customer is considering using FXLS8471Q.
They want the Mechanical Resonance(-3dB) or the Mechanical Signal Bandwidth(-3dB) to compare the performance with other maker's sensor.
However, NXP's data sheet does not have this specification.

If so, please tell me why.

Best Regards,

George

Dear George,

The mechanical resonance frequency is 3.56 kHz for XY and 2.74 kHz for Z-axis.

Best regards,

Tomas

Dear TomasVaverka‌,

Thank you for your quick reply.

Just to make sure, the frequency you say is -3dB point, right?

Thanks,

George

Dear George,

No, those are natural mechanical resonant frequencies of the FXLS8471Q.

Best regards,

Tomas
