TA2056FN

The TA2056FN is an infrared ray linear audio signal receiver IC developed for IR cordless headphone systems.It is two built in FM receivers for stereo and muting function etc.

Features of the TA2056FN are:(1)two built-in FM reveivers for stereo (f=2.3/2.8MHz);(2)excellent spurious radiation by direct detection type;(3)built-in muting function (retuned noise detection type):built-in buffer amplifier for muting signal detection,built-in muting amplifier,built-in detector circuit,muting attenuation (VCC=1.2V,Ta=25) ATT=65dB(Typ.);(4)two built-in RF amplifiers;(5)low supply current (VCC=1.2V,Ta=25) ICC=4.0mA(Typ.);(6)operating supply voltage range (Ta=25) VCC(opr)=0.95 to 2.2V.

The maximum ratings of the TA2056FN can be summarized as:(1):the characteristic is supply voltage,the symbol is VCC,the rating is 3,the unit is V;(2):the characteristic is power dissipation,the symbol is PD,the rating is 500,the unit is mW;(3):the characteristic is equalizer current,the symbol is IEQ,the rating is 50,the unit is mA;(4):the characteristic is operating temperature range,the symbol is Topr,the rating is -25 to 75,the unit is ;(5):the characteristic is storage temperature range,the symbol is Tstg,the rating is -55 to 150,the unit is .
