Quality Factors

Figure 6 shows the four possible quality factors 1, 1.25, 1.5 and 2.

DC Mode

In this mode the DC-gain is increased by 5.1dB. 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.

Note: In general the center frequency, Q and DC-mode can be set independently. The exception from this

rule is the mode (5/xx1111xx) where the center frequency is set to 150Hz instead of 100Hz.
