TDA7404
Description of functionality
4.7.4
DC mode
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.
Figure 13.
Bass normal and DC mode @ gain = 14 dB, fC = 80 Hz
1.
The center frequency, Q and DC mode can be set fully independently.
