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. 

 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
