TA8123AF

TA8122, 23AN / AF TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8122AN, TA8122AF, TA8123AN, TA8123AF 3V AV / FM 1Chip Tuner IC TA8122AN / AF and TA8123AN / AF are the AM / FM 1chip tuner ICs, which are designed for portable radios and 3V headphone radios. Features · Built−in FM F / E, AM / FM IF and FM ST DET · AM detector coil, FM IFT and IF coupling condenser are not needed. · For adopting ceramic discriminator and ceramic resonator, it is not necessary to adjust the FM quad detector Circuit and FM ST DET VCO circuit. · S curve characteristics of FM detection output in TA8122AN / AF and TA8123AN / AF are reverse to each other. TA8122AN / AF: Reverse characteristic TA8123AN / AF: Normal characteristic · Compact pakage TA8122AN / 23AN: Shrink DIP 24 pin (1.78mm pitch) TA8122AF / 23AF: Mini flat package 24 pin · Operating supply voltage range VCC = 1.8~7.0V (Ta = 25°C) Weight SDIP24−P−300−1.78: 1.2g (typ.) SSOP24−P−300−1.00: 0.31g (typ.) 1 2002-10-30 Block Diagram TA8122, 23AN / AF (Note) We recommend the kit of the ceramic filter and the ceramic resonator which are shown in the table as below. It is necessary to meet the center frequency of the ceramic filter and the ceramic resonator, otherwise there are some cases that the characteristics get worse.
