SILAN SA2132

SA2132
AM/FM RADIO RECEIVER
DESCRIPTION
SA2132 is AM/FM radio IC (FM F/E+AM/FM IF) which is designed for
AM/FM radios.
SOP-16-225-1.27
FM local oscillation voltage is set up low relativity, for NEW FCC.
FEATURES
* For NEW FCC
* AM detector coil, FM IFT, IF coupling condenser are not needed.
DIP-16-300-2.54
* For adopting ceramic discriminator, it is not necessary to adjust the
FM quad detector circuit.
* Built in varactor diode for AFC
* Low supply current: (VCC=3V, TA=25°C)
ORDERING INFORMATION
ICCq (FM)=7.3mA (typ.)
Device
ICCq (AM)=3.6mA (typ.)
* Operating supply voltage range: VCC=1.8~7V (TA=25°C)
