I want to use this part for a project where low noise is essential.
I will restrict the ODR to 62 Hz and set the LPF to 15 Hz.
Will that decrease the output noise to 25 ug √ 15 = 96.8 ug?
Thank you for posting this question.
This is pretty close, but I would probably assume a single-pole roll-off, which means that the noise bandwidth would be 1.6 x cut-off frequency (15Hz).
Noise = 0.025 x sqrt(1.6 x 15) = ~122ug
I hope that this helps!
Yes, it helps indeed, the content in the 20 dB slope also adds its extra bit.
I might have to go for the full bandwidth and use my own filters.
That sounds like a good way for you to optimize the trade-off between Total noise vs Responsiveness. Thanks for sharing this! Good luck with your project.
I was considering a multiple-sensor system to correlate the signal and cancel random noise, but could as well use it at full ODR and average and downsample to increase the SNR.
