Overview:

D3361 is a low-power narrow-band FM if circuit. Includes a complete set of narrow-band FM detection systems capable of operating at supply voltage below 2V. The low-power narrow-band FM intermediate amplifier system includes a second frequency conversion, a second intermediate amplifier, a frequency discriminator, filtering and amplifying, and a mute module which can provide communication and scanning signals. Used in frequency modulation communication switches.

 

Main features:

● Working voltage range: 2.0V~ 8.0V
● Current loss small ICC=4.0mA typical (VCC=4.0V)
● High input sensitivity (-3dB limit = 2.0μ Vrms are typical.)
● Working frequency up to 60 MHz
● Few external components
● Encapsulation form: DIP16, SOP16

 

 

Application:

● Frequency modulation communication switch
