AFT OUTPUT
AFT output.
AFT center voltage is generated by an external
bleeder.
The AFT gain is increased by increasing the
resistance of this external bleeder resister.

SIF BPF OUTPUT
The output to the external bandpass filter is passed
through an internal 6dB amplifier before being
output.
23
AUDIO OUTPUT
Audio FM detector output. A 54K
resister is
inserted in series with an emitter-follower output.
For applications that support mono:
Create an external deemphasis circuit.
t = C 1

24
AUDIO BIAS FILTER
Connection for a filter used to hold the FM detector
output DC voltage fixed. Normally, a 1
μ
F electrolytic
capacitor should be used. The capacitance should
be increased if the low band (around 50Hz)
frequency characteristics need to be improved.
The FM detector output level can be reduced and the
FM dynamic range can be increased by inserting a
resistor and a capacitor in series between pin 24 and
GND.
