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.
FM local oscillation voltage is set up low relativity, for NEW FCC.
SOP-16-225-1.27
FEATURES
* For NEW FCC
* AM detector coil, FM IFT, IF coupling condenser are not needed.
* For adopting ceramic discriminator, it is not necessary to adjust the
FM quad detector circuit.
* Built in varactor diode for AFC
* Low supply current: (V
