4. Frequency characteristics
The AN6123MS itself has an almost flat fre-
quency characteristic in the audio frequency band.
The high-band frequency is set with R and C
shown in the left circuit. The cut-off frequency f
C
at R
=
10 k
and C
=
2 200 pF, that is the frequency
at which the frequency characteristic deteriorates
by 3 dB, is f

CR
=
7.2 kHz. At R
=
10 k
and C
=
1 000 pF, it is 16 kHz. (Refer to the graph.)
