APPLICATION INFORMATION
External Components
C

(C
9
): Input coupling capacitor
These components are concerned with the output noise and operation starting time. Its capacitance is ade-
quate for 10
μ
F.
As C2 (C9) below 4.7
μ
F extends the operation starting time, a capacitance of over 4.8
μ
F is recommended.
C

): Negative feedback capacitor
These components decide the low cut-off frequency, which is determined as follows:

): Equalizer network
These components decide the frequency response of an equalizer amplifier. The time constant of standard
NAB characteristic is as follows:

Filter capacitor of the power line
This should be located as close to the supply voltage pin (Pin 4) as possible. The recommended value is 47
μ
F.
C
1
(C
10
): Protection capacitor
These components protect against wave damage of strong electric fields. They also protect against engine
noise damage and block oscillation during high amplifying operations.
