Hello again electronics people!
Thanks for your replies that are helping me with my project.
I now received my sensor and ADC.
Their sizes really surprised me. The sensor can be soldered with QFN method without problem. I'm using KiCAD software to build the PCB.
But when I received the ADC...
Hello, thank you for these constructive replies, you're being very helpful.
KLAUS:
The sensor's
Got it!! so a 3rd order Low pass filter. I can use Butterworth or other? Sorry I forgot the notion of the filters.
For future work I'm looking forward buying a simultaneous sampling one. For the...
I have a norm that I should follow (EN1177). The sensor's frequency range is minimum between 1 and 1000Hz.
Also in the norm, we need a sampling rate higher than 20KSPS per channel(Axis). They stated that we need an anti-aliasing filter with -30dB at the half of the sampling rate.
Heyy, I am sorry for the lack of clarification.
For the math I got it, like you said it's not rocket science
So I should not look at the "natural response given by the datasheet, only at my frequency response (2-6000Hz).
Do we agree that my ADC does not simultaneous sampling? So if I am...
Hello,
Thank you for your reply.
In fact, using the formula, if we have 3.3V as AVDD, 0.4V will yield to 496, and 2.9V to 3600.
How to have -500 and 500 as readings. Should I use a mapping function or something like that?
My application requires 12-bit resolution, and the natural response...
Hello,
I found a 3-axial accelerometer with +/-500g that has a +/-1.25V range. The bias voltage (0g) is at half of the reference given (It does not give negative voltage).
If I'm supplying it with 3.3V, the bias voltage will be at 1.65V, so the range will be nominally 0.4V to 2.9V.
I am to read...
