NJU7181 Datasheet (New Japan Radio) - SIGNAL LEVEL SENSOR SYSTEM

NJU7181, SIGNAL LEVEL SENSOR SYSTEM

The NJU7181 is a signal level sensor system IC.

It sends a High flag to the microprocessor or other equipments whenever it detects the existence of the audio signal.

The NJU7181 includes a delay circuit which allows the IC continue to hold the flag after the absence of the audio signal.
