Hi everyone
I'm not an EE by any means, i guess this could be a simple question but...
What does the letter 'B' stands in this datasheet formula?



It's found here, page 10

It's the noise band.
From p4 of the datasheet:

Oh missed that one! now i see. Thanks a lot!
So the number i should use in the formula it's the range from 22 to 22k (21,978)?

I assume you have a free choice as to the noise band you specify and that the datasheet is merely giving a typical example.

Yeah the range in the datasheet it's totally fine since I'll use it for audio, i was wondering how to find the value of C8 given the noise band
