TA8145FN

The TA8145FN is a stereo headphone power amplifier IC,wgich is developed for low voltage operation (1.5V).It is especially suitable for a stereo headphone cassette player.

Features of the TA8145FN are:(1)OCL (output condenser-less);(2)built-in a ripple filter;(3)GV=22dB (Typ.);(4)output power : Po=8mW (Typ.) (VCC=1.5V,RL=16,THD=10%,Ta=25);(5)built-ib a power switch;(6)built-in a power amplifier mute;(7)excellent ripple rejection ratio : RR=52dB(Typ.);(8)low noise : Vno=27Vrms (Typ.);(9)operating supply voltage range (Ta=25) VCC(opr) =0.9 to 2.2V.

The maximum ratings of the TA8145FN can be summarized as:(1):the characteristic is supply voltage (motor),the symbol is VM,the rating is 4.5,the unit is V;(2):the characteristic is output current power ampilifier,the symbol is IO(peak),the rating is 60,the unit is mA;(4):the characteristic is output current ripple filter (built-in transistor),the symbol is IRF,the rating is 5,the unit is mA;(5):the characteristic is power dissipation,the symbol is PD,the rating is 400,the unit is mW;(6):the characteristic is operating temperature,the symbol is Topr,the rating is -25 to 75,the unit is ;(7):the characteristic is storage temperature,the symbol is Tstg,the rating is -55 to 150,the unit is .
