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 = 3.5~14V (Ta = 25°C)
