KA22211 DUAL LOW NOISE EQ AMP
APPLICATION INFORMATION
External Components
C
2
(C
9
): Input coupling capacitor
These components are concerned with the output noise and operation starting time, and its capacitance
is adequate for 10
μ
F.
As C2 (C9) below 4.7
μ
F extends the operation starting time, a capactance of over 4.8
μ
F is recommended.
C
3
(C
8
): Negative feeback capacitor
These components decide the low cut-off frequency, which is determined as follows:
C
3
(C
8
) =
where, f
: low cut-off frequency.
A large C
3
(C
8
) makes the operation starting time of an amplifier late. Its capacitance is adequate for
47
μ
F.

2
(C
, R
, R
): Equalizer network
These components decied the frequency response of an equalizer amplifier. The time constant of standard
NAB characteristic is as follows:
C
11
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 is strong electric fields and engine noise damage and
block oscillation at high amplifying operation.
C
5
(C
6
): Output coupling capacitor
The recommended value is 10
μ
F.
