Audio ICs
BA3812L
By using more than one IC the following applications are
also possible:
(1) 10-point single-channel graphic equalizer
As shown in Fig. 2, with two ICs it is possible to construct
a 10-point single-channel graphic equalizer,
(2) 7-point stereo graphic equalizer
As shown in Fig. 3, with three ICs it is possible to
construct a 7-point stereo graphic equalizer. Two
BA3812L ICs are used to construct a 5-point stereo
graphic equalizer, and two of the active inductor circuits
from a third BA3812L are added to each.
