TA2057N Datasheet

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic


AM / FM IF + FM St DET (for digital tuning system)

TA2057N is the AM / FM IF + FM St DET system IC, which is designed for DTS radios. This IC is included many functions and these can be used for digital tuning system with IF counter. 

Suitable for combination with digital tuning system which has IF counter.
One terminal type AM / FM IF count output (auto stop signal) for IF counter of digitl tuning system.
Built−in mute circuit for IF count output.
Adjustable for IF count output sensitivity by external resistance of pin(2) (AM), and pin(3) (FM).
For adopting ceramic discriminator and ceramic resonator, it is not necessary to adjust the FM quad detector
circuit and FM st DET vco circuit.
Built−in AM local oscillator buffer output circuit.
Built−in AM IF buffer output circuit for AM stereo.
Operating supply voltage range (Ta = 25°C): VCC= 3.5~14V
