TA2002F

The TA2002F is developed for play-back stereo headphone equipments(3V use).They are built in dual auto-reverse preamplifier,dual OCL power amplifier,and a ripple filter.

Features of the TA2002F are:(1)power amplifier stage:OCL,low noise is Vno=22Vrms(Typ.),excellent ripple rejection ratio is RR=62dB(Typ.),voltage gain is GV=27dB(Typ.),built-in a power amplifier mute,built-in input capacitor for reducing buzz noise;(2)preamplifier stage:auto-reverse with F/R control switch,input coupling condenser-less,low noise is Vni=1.3Vrms(Typ.),built-in a preamplifier mute,built-in input capacitor for reducing buzz noise;(3)total:built-in a ripple filter,built-in a power switch,low quiescent current is ICCQ=11.5mA(Typ.)(VCC=3V,Ta=25),operating supply voltage range is VCC(opr)=1.8 to 4.5V(Ta=25).

The maximum ratings of the TA2002F can be summarized as:(1):the characteristic is supply voltage,the symbol is VCC,the rating is 6,the unit is V;(2):the characteristic is output current power,the symbol is Io(peak),the rating is 60,the unit is mA;(3):the characteristic is output current ripple filter,the symbol is IRF,the rating is 30,the unit is mA;(4):the characteristic is power dissipation,the symbol is PD,the rating is 400,the unit is mW;(5):the characteristic is operating temperature range,the symbol is Topr,the rating is -25 to 75,the unit is ;(6):the characteristic is storage temperature range,the symbol is Tstg,the rating is -55 to 150,the unit is .
