3V AM / FM IF + MPX
(For Digital Tuning System)
TA8132ANG, TA8132AFG and TA2012NG, TA2012FG 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
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 TA8132ANG, TA8132AFG and TA2012NG, TA2012FG are
reverse to each other.
Built−in one terminal type AM low cut circuit.
TA2053F is reverse pin type of TA2012FG.
Operating supply voltage range (Ta = 25°C)
