TA2140FN

The TA2140FN is designed as one kind of 1 chip tuner ICs which designed for portable radios and 3 V Head phone radios. Features of the TA2140FN are:(1)operating supply voltage range:Vcc=1.8 to 7 V (Ta=25°C);(2)low supply current;(3)built-in AM low cut circuit;(4)built-in 1/16 pre-scaler for FM local OSC buffer;(5)built-in one terminal type AM/FM local oscillator buffer output for digital tuning system applications;(6)built-in FM MPX VCO circuit;(7)for adopting ceramic Discriminator, it is not necessary to adjust the FM quad detector circuit;(8)built-in mute circuit for IF count output;(9)for NEW FCC;(10)suitable for combination with digital tuning system which is included IF counter.

The absolute maximum ratings of the TA2140FN can be summarized as:(1)supply voltage:8 V;(2)LED current:10 mA;(3)LED voltage:8 V;(4)power dissipation: 1200 mW;(5)operating temperature:-25 to 75°C;(6)storage temperature:-55 to 150°C.
