TA2008AN

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 = 3.5~14V (Ta = 25°C) 1 2002-10-30 TA2008AN 2 2002-10-30 Explanation Of Terminals Pin No. Characteristic 1 FM-RF in 2 GND1 (GND for RF stage) 3 Mix out Internal Circuit ― TA2008AN DC Voltage (V) (at no signal) AM FM 0 0.8 00 0.3 0.8 4 AGC 5 VCC2 (VCC for IF / FM ST DET stage) 6 FM IF in 1.2 0.9 ― 5.0 5.0 5.0 5.0 3 2002-10-30 Pin No. Characteristic 7 AM IF in 8 GND2 (GND for if / FM ST DET stage) 9 QUAD (FM QUAD.
