TA8132 Datasheet

Bipolar Linear Integrated Circuit Silicon Monolithic


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.

• 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. 
• 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 voltage range (Ta = 25°C)
   VCC (opr.)= 1.8~8.0V
