Bandpass filter output
The output to the external bandpass filter is passed
through an internal 6 dB amplifier before being output.

Filter that holds the FM detector output DC voltage
fixed.
Normally, a 1 μF electrolytic capacitor is used. If the
low band (around 50 Hz) frequency characteristics are
of concern, this value should be increased. The FM
detection output level can be reduced and the FM
dynamic range improved by inserting the resistor R in
series with the capacitor between pin 23 and ground.

inserted in series.
Stereo applications
In some application that provide input to a stereo
decoder, the input impedance may be reduced,
resulting in distortion in the L-R signal and degraded
stereo characteristics. If this problem occurs, add a
resistor between pin 24 and ground.
