1. This parameter is given as application information and is not tested during production.
2. Without external control voltage at pin 13, the internal FM is demodulated.
3. Without control voltage at pin 11, the audio signal from switch 1 is automatically selected.
amb
With V11 < 1.5 or V11 > 4.0V input pin 10 is selected.
= +25°C; reference point pin 4, unless otherwise specified.
