(13) DC control
There is internal impedance of 10k
at the VC (pin 23),
TC (pin 22), and BC (pin 21) pins, and internal imped-
ance of 200k
at the SC pin (pin 11). For this reason, it
is recommended that DC control of these pins be per-
formed by voltage delivered directly from the voltage
source. When using variable volume, take the imped-
ance into account in determining the settings.
Note: The voltage range for DC control is 0V to 3.8V. Be
sure not to apply greater than 3.8V to any pin.
(14) GND
Connect the GND of the attached element, which is
shown in the circuit of the sample application, to the
analog GND.
Connect the GND of the capacitor that is connected to
pin 17 to the digital GND.
If several capacitors with good high-frequency charac-
teristics are connected in parallel to the 17th-pin capac-
itor, the characteristics will be improved with respect to
static electricity noise. (Recommended: ceramic ca-
pacitors of 0.001
μ
F to 0.1
μ
F) If the wiring to the analog
GND and digital GND is long, make sure that no poten-
tial difference arises between the two GNDs.
(15) BH3854AS
The bass filter R
2
constant changes from 100 k
k
. Accordingly, bass filter f
0
changes from 70Hz
75Hz, which means bass filter Q changes from 1.47
1.36.
The resistance at the treble filter’s TIN pin changes
from 20 k
2 k
. Accordingly, the value for the at-
tached capacitor changes from 470pF
which means that cutoff frequency (f
C
1
) changes from
17kHz
8kHz.
