DC mode
It is used for cut only for shelving filter. In this mode the DC gain is increased by 4.4 dB. In
addition the programmed center frequency and quality factor is decreased by 25 % which
can be used to reach alternative center frequencies or quality factors.

Middle
There are three parameters programmable in the middle stage:
Attenuation

Figure 13. Middle control @ f
shows the attenuation as a function of frequency at a center frequency of 1 kHz.
