Pin No.
Function
Description
Equivalent circuit
Continued from preceding page.
Continued on next page.
The HCC frequency characteristics
are determined by the external
capacitor connected at this pin.
41
HCC capacitor
This pin is used to change the
frequency characteristics of the
unneeded audio band under
100 Hz in AM mode to produce
a clear audio signal.
Note: The LC capacitor must be
connected between this pin
and V
CC
(pin 40).
This is because the detector
circuit operates referenced
to V
CC
.
42
AM L.C. pin
The cutoff frequency f
C
is
determined by the following
formula.
f
C
= 1/2
π ×
50 k
×
C
Inserting a 1-M
resistor between
pin 43 and V
CC
will force the IC
to mono mode.
