Description of External Components
C1, C4
Input capacitors
2.2
F is recommended. fL can be varied by C1, C4 capacitances to adjust the bass range.
C2
Decoupling capacitor
(ripple filter)
C3
Amplifier on time setting
capacitor
Approximately 0.8 second for 33
F. Since the on time is proportional to this capacitance, it can
be set as desired by varying this capacitance. (Refer to the characteristics curve.)
C5
Power supply capacitor
C6, C7, C8, C9
Oscillation blocking capacitors
Use polyester film capacitors (Mylar capacitors) with good temperature characteristics. (R2, R3,
R4, and R5 used jointly.) Since stability may be affected slightly by the pattern layout, etc.,
0.1
F or more is recommended.
R1
Standby switch current
limiting resistor
10k
is recommended (when the applied voltage for the standby switch is 2.5V to 13.2V). This
resistor cannot be removed.
