TA8157AF

The TA8157AF is developed for play-back stereo headphone equipments at low voltage operation(1.5V use).

Features of the TA8157AF are:(1)OCL (output condenser less);(2)built-in ripple filter;(3)output power(Vcc=1.5V,f=1kHz,THD=10%,RL=16) Po=9mW(Typ.);(4)voltage gain is GV=24dB(Typ.);(5)built-in boost amplifier;(6)built-in power switch;(7)built-in muting circuit;(8)low quiescent supply current (Ta=25) ICCQ=8mA(Typ.);(9)excellent ripple rejection ratio is RR=55dB(Typ.);(10)low noise is Vno=25Vrms(Typ.);(11)operating supply voltage range (Ta=25) VCC(opr)=0.9 to 2.2V.

The maximum ratings of the TA8157AF 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 output current,the symbol is IO(peak),the rating is 100,the unit is mA;(3):the characteristic is power dissipation,the symbol is PD,the rating is 400,the unit is mW;(4):the characteristic is operating temperature,the symbol is Topr,the rating is -25 to 75,the unit is ;(5):the characteristic is storage temperature,the symbol is Tstg,the rating is -55 to 150,the unit is .
