TA2008AN
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA2008AN
5V AM / FM 1 Chip Tuner IC (for digital tuning system)
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 = 3.5~14V (Ta = 25C)
