8. FM / AM switch and forced monaural switch
FM / AM switch over and stere / forced monaural switch over are done by
internal PNP transistors ON / OFF which are connected to pin(16) and pin
(17) respectively.
The threshold voltages of these PNP transistors are V
switching, we recommend to use mechanical switch.
(Direct short to V
In the case of the electrical switch over by transistor, set up V
(saturation voltage between collector and emitter) 50mV or less, otherwise
there are some cases that it does not become the AM mode and force
monaural mode.
When these external switches are ON, the currents which flow into pin(16)
and pin(17) are 100µA and 20µA respectively. (Typical value at V
