It is recommended that DC control of the VC, TC, BC, and
SC pins be performed by voltage delivered in variable
volume from the V
volume, take the discharge current of each pin into ac-
count in determining its settings.
Note:The voltage range for DC control is 0 (V) to V
Be sure not to apply voltage greater than V
pin.

If several capacitors with good high-frequency charac-
teristics are connected in parallel to the 12th-pin capaci-
tor, the characteristics will be improved with respect to
static electricity noise. (Recommended : ceramic capaci-
tors of 0.001 F to 0.1 F)
