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 Vth = VCC, and for

switching, we recommend to use mechanical switch.

(Direct short to VCC line.)

In the case of the electrical switch over by transistor, set up VCE

(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 VCC = 3V)
