TA2022AFN

The TA2022AFN is the AM/FM IF+MPX system IC,which is developed for headphone radio in 1.5V use.This is included many functions and this can be used for digital tuning system with IF counter.

Features of the TA2022AFN are:(1)suitable for combination with digital tuning system which is included IF counter;(2)for adopting ceramic discriminator,it is not necessary to adjust the FM QUAD detector circuit;(3)built-in AM IF output for AM stereo;(4)MPX input for main signal is independent of that for pilot signal;(5)MPX output is high-impedance in power off mode;(6)built-in power switch;(7)low supply current(VCC=1.2V,Ta=25);(8)operating supply voltage range (Ta=25) VCC(opr)=0.95 to 2.2V;(9)stereo operating supply voltage range (Ta=25) VCC(opr)=1.0 to 2.2V.

The maximum ratings of the TA2022AFN can be summarized as:(1):the characteristic is supply voltage,the symbol is VCC,the rating is 4.5,the unit is V;(2):the characteristic is stop pulse voltage,the symbol is VSP,the rating is 4.5,the unit is V;(3):the characteristic is stop pulse current,the symbol is ISP,the rating is 10,the unit is mA;(4):the characteristic is stereo indicator voltage,the symbol is VST,the rating is 4.5,the unit is V;(5):the characteristic is stereo indicator current,the symbol is IST,the rating is 10,the unit is mA;(6):the characteristic is power dissipation,the symbol is PD,the rating is 500,the unit is mW;(7):the characteristic is operating temperature range,the symbol is Topr,the rating is -25 to 75,the unit is ;(8):the characteristic is storage temperature range,the symbol is Tstg,the rating is -55 to 150,the unit is .
