TA2057N Description
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA2057N AM / FM IF + FM St DET (for digital tuning system) TA2057N 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.
TA2057N Key Features
- Suitable for bination 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
- 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
- IF count output terminal
- IF count output / FM st DET mute circuit control terminal
