(Metal-plate resistor is recommended.)
output Power
runaway
Select restriction resistance, for the impression voltage of ‘#17 (Stand-By) pin’ must not exceed the maximum
rating.
Capacitor for oscillation prevention.
• Locate near the HIC as much as possible.
• Power supply impedance is lowered and stable
-
-
operation of the IC is carried out. (Electrolytic capacitor
is recommended.)
Decoupling capacitor
The change in the ripple ingredient mixed in an input
• The ripple ingredient mixed in an input side is removed side from a power supply line
from a power supply line. (Ripple filter is constituted
with R03, R04.)
Input coupling capacitor. (for DC current prevention.)
-
C07, C08, C09 470pF
C10, C11, C12 3pF
Input filter capacitor
• A high frequency noise is reduced with the filter
constituted by R02, R03, R04.
Capacitor for oscillation prevention.
-
It may oscillate.
C13, C14, C15 10μF/10V
Negative feedback capacitor.
• The cutoff frequency of a low cycle changes.
(fL=1/(2π ⋅ C13 ⋅ R11))
C16, C17, C18 0.1μF
Capacitor for oscillation prevention.
The voltage gain (VG)
of low frequency is
extended. However, the
pop noise at the time of
a power supply injection
also becomes large.
It may oscillate.
The voltage gain (VG)
of low frequency
decreases.
C19, C20, C21 68pF
