5. AM local oscillator buffer output

· The output impedance of AM local oscillator buffer output pin (pin(4)) is 750Ω (typ.) (cf.P.3)

So, in the case that it is connected to other circuits, take care of the input capacity of these circuits and stray

capacity of wire.

6. Tuning LED driver and stereo LED driver

shown in the right figure. So, it is necessary to add the current limit resistance:

7.FM detection circuit

For the FM detection circuit,detection coil is able to use instead of ceramic discriminator.

Recommended circuit and recommended coil are as follows.
