TA8205AH

The thermal resistance j-T of TA8205AH, TAS205AL package designed for low thermal resistance which has a high efficiency of heat radiation. This stereo audio power IC, designed for car audio use, has two built-in channels to reduce the characteristic difference between and channels. The temperature rise of chip can be reduced, and the influence from the degradation of the features due to the temperature rise at the high output can also be reduced. In addition, the functions of stand-by and muting, and a variety of protection circuits are involved.

The features of TA8205AH can be summarized as (1)low thermal resistance: j-T=1.5°C/W (infinite heat sink); (2)high power: POUT m=18W (Typ.)/Channel (VCC= 14.4V, f= THD= 10%, RL=4) POUT = 15W(Typ.)/channel (VCC=13.2V, f=1kHz, THD= 10%, RL=4); (3)low distortion ratio: THD=0.04% (VCC=13.2V, f=1kHz, POU-r=1W, GV=50dB); (4)low noise: VNo=0.30mVrmS (VCC=13.2V, RL=4, GV=50dB, Rg=0, BW=20Hz~20kHz); (5)built-in stand-by function (with pin set at LOW, power is turned OFF.): lSB=1A(typ); (6)built-in muting function (with pin set at Low, power is turned OFF.): V(Mute)=1V(typ); (7)built-in various protection circuits protection circuits: thermal shut down, over voltage, out->Vgg short, out->GND short and OUT- OUT short; (8)operating supply voltage : VCC=9~18V.

The absolute maximum ratings of TA8205AH are (1)peak supply voltage VCC (surge): 50V; (2)DC supply voltage VCC DC: 25V; (3)operating supply voltage VCC(opr): 18V; (4)output current (peak) IO(peak): 9A; (5)power dissipation PD: 50W; (6)operating temperature Topr: -30~ 85°C; (7)storage temperature Tstg: - 55~150°C.
