TA8132AN

TA8132AN / AF , TA2012N / F TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8132AN,TA8132AF,TA2012N,TA2012F 3V AM / FM IF + MPX (For Digital Tuning System) TA8132AN, TA8132AF and TA2012N, TA2012F are the AM / FM IF+ST DET system ICs, which are designed for DTS radios. These are included many functions and these can be used for digital tuning system with IF counter. Features · · Built−in AM / FM IF and FM stereo PLL multiplex decoder. Suitable for combination with digital tuning system which is included IF counter. ○ One terminal type AM / FM IF count output (auto stop signal) for IF counter of digital tuning system. FM: 10.7MHz or 1.3375MHz (1 / 8 dividing) changeable by external switch AM: 450kHz ○ Built−in mute circuit for IF count output. It is controlled by the IF request signal from digital tuning system, Pin(8) level: High → come out Low → non output ○ Adjustable for IF count output sensitivity by external resistance of pin(2). · For adopting ceramic discriminator and ceramic resonator, it is not necessary to adjust the FM quad detector circuit and FM ST DET VCO circuit. Weight SDIP24−P−300−1.78: 1.2g (typ.) SSOP24−P−300−1.00 : 0.31g (typ.) · S curve characteristics of FM detection output in TA8132AN, TA8132AF and TA2012N, TA2012F are reverse to each other. TA8132AN, TA8132AF: Reverse characteristic. TA2012N, TA2012F: Normal characteristic. · · · Built−in one terminal type AM low cut circuit. TA2053F is reverse pin type of TA2012F. Operating supply ...
