SA2003 AM/FM RADIO RECEIVER DESCRIPTION The SA2003 is AM/FM radio IC (FM F/E+AM/FM IF) which is designed for AM/FM radios. Combining with the UTC7368 (Mono PW IC), a suitable AM/FM radio system is able to be constituted. DIP-16-300-2.54 FEATURES * FM IFT, AM IFT and FM detector coil are not needed. * Pin compatible of TA8164P. SOP-16-225-1.27 * Operating supply voltage range: VCC(opr)=1.8~7V (Ta=25°C) ORDERING INFORMATION Device Package SA2003 DIP-16-300-2.54 SA2003S SOP-16-225-1.27 BLOCK DIAGRAM ABSOLUTE MAXIMUM RATINGS (Tamb=25°C) Characteristic Supply Voltage Power Dissipation DIP-16 SOP-16 Symbol Ratings Unit VCC 8 V PD (Note) 750 mW 350 Operating Temperature Topr -25~75 °C Storage Temperature Tstg -55~150 °C NOTE: Derated above Tamb=25°C in the proportion of 6mW/°C for SA2003 and of 2.8 mW/°C for SA2002S.
