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) Package SA2132 DIP-16-300-2.54 SA2132S SOP-16-225-1.27 BLOCK DIAGRAM AM RF IN FM RF OUT AM/FM SW FM OSC AM OSC AFC DET OUT QUAD 16 15 14 13 12 11 10 9 FM/AM FM OSC AM OSC AM RF AF BUFF FM DET AM DET FM MIX FMRF AM MIX AGC FMIF AMIF 1 2 3 4 5 6 7 8 FM RF IN RF GND MIX OUT AGC VCC FM IF IN AM IF IN GND ABSOLUTE MAXIMUM RATINGS (TA=25°C) Characteristic Supply Voltage Power Dissipation Symbol Value Unit VCC 8 V PD (Note 1) 750 mW Operating Temperature Topr -25~75 °C Storage Temperature Tstg -55~150 °C Note 1: Detected above TA= 25°C in the proportion of 6mW/°C for SA2132.
