Overview

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA2008AN 5V AM / FM 1 Chip Tuner IC (for digital tuning system) TA2008AN The TA2008AN is the AM / FM 1 chip tuner IC, which is designed for radio cassette players and music centers.
This is suitable for digital tuning system applications.
Features · 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: 1.
3375MHz (1 / 8 dividing) · AM: 450kHz · Built−in mute circuit for IF count output.
Weight: 1.
2g (typ.
) · For adopting ceramic discriminator and ceramic resonator, it is not necessary to adjust the FM quad detector circuit and FM stereo detector vco circuit.
· Built−in one terminal type AM / FM local oscillator buffer output for digital tuning system applications.
· Operating supply voltage range: VCC = 3.
