3V AV / FM 1Chip Tuner IC
TA8122ANG / AFG and TA8123ANG / AFG are the AM / FM
1chip tuner ICs, which are designed for portable radios and 3V
headphone radios.
Features
Built−in
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 TA8122ANG
/ AFG and TA8123ANG / AFG are reverse to each other.
Compact pakage
Operating supply voltage range
FM F / E, AM / FM IF and FM ST DET
TA8122ANG / AFG: Reverse characteristic
TA8123ANG / AFG: Normal characteristic
