Pin function
Equivalent circuit
FM filter
Connection for a filter used to hold the FM detector output at
a fixed DC voltage.
Normally, a 1-F electrolytic capacitor is used. If the low
area (around 50 Hz) frequency characteristics are seen as a
problem, this capacitance should be increased.

FM detector output
Audio FM detector output.
A 200-
resistor is inserted in series after the emitter
follower.
In applications that support stereo:
In applications that input to a stereo decoder, the reduced
input impedance can cause distortion in the L-R signal. This
may degrade the stereo characteristics. If this is a problem
add the resistor R1 between pin 24 and ground.
R1
≥ 5.1 k
In applications that support mono:
Attach an external de-emphasis circuit with the following
time constant.
t = CR2
