SA2111C
3V AM/FM +MPX TUNER IC(FOR MECHANICAL TUNING)
DESCRIPTION
The SA2111C is AM/FM single-chip tuner IC, which is designed for
portable radios and 3V head phone radios. It is suitable for digit tuning
system, and FM local oscillation voltage is set up low relativity, for NEW
FCC.
SSOP-24-300-0.65 SSOP-24-300-1.0
FEATURES
* Operating supply voltage range: VCC=1.8~7V (Tamb=25°C)
* AM detector coil, FM IFT, IF coupling condenser are not needed.
SOP-24-375-1.27 SDIP-24-300-1.778
* For adopting ceramic discriminator, it is not necessary to adjust the
FM quad detector circuit.
* Built-in FM MPX VCO circuit
* Built-in varactor diode for AFC
ORDERING INFORMATION
* Built-in AM low cut circuit
* Low supply current. (VCC=3V, Tamb=25°C)
ICCq(FM)=9.0mA (Typ.)
ICCq(AM)=5.0mA (Typ.)
Note: Handle with care to prevent devices from deteriorations by
ESD.
