Tool/software:
Hi,
There are a few points I need clarification on about setting BQ resisters.
In the datasheet in section 7.5.2.4 (BQ Gain Scale) it says: "The BQ coefficients format is as follows: The *first* BQ has B0 = 5.x, B1 = 6.x, B2 = 5.x, A1 = 2.x, and A2 = 1.x." But in slaa799a.pdf the *last* BQ seems to be gain scale. Which one is correct?
I thought the general idea to set the gain of every BQ to be less than 1, and then make up for it in the last BQ, but then there is this sentence in section 7.5.2.4: "The calculated k_BQ compensation value is then applied to the BQ gain scale in an 8.24 format." Now I'm confused. Where does the 8.24 come from? looking at slaa799a.pdf, none of the registers are in 8.24 format.
Your clarification is much appreciated.
Thanks
