Pin No.
Pin name
Function
Equivalent circuit
22
BPF OUT
Band-pass filter output.
The output to the external band-pass filter is passed
through an internal amplifier before being output.
23
FM FILTER
Filter that holds the FM detector output DC voltage fixed.
Normally, a 1
μ
F electrolytic capacitor is used.
If the low band (around 50Hz) 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.
24
FM DET OUT
Audio FM detector output.
This is an emitter-follower circuit with a 300
resistor
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.

Mono applications.
Construct an external de-emphasis circuit.
