Signal Level Sensor System

Manufacturer's part number :

NJU7181KU1

Manufacturer New Japan Radio

New Japan Radio

Description :

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. This holding time can be adjusted with external capacitor.

Together with its adjustable Input Sensitivity (by external resistor) and its characteristic of low current consumption and low operating voltage, NJU7181 is suitable for Eco-Design of Energy-using Products and for battery operated applications.
