TA8221AH

The TA8221AH is a kind of thermal resistance j-T package which is designed for low thermal resistance, 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. It also contains various kind of protection. 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.

The features of TA8221AH can be summarized as (1)low thermal resistance: j-T=1.5°C/W (Infinite Heat sink); (2)high power POUT(1)=30W(typ)/channel(VCC= 14.4v, f=1kHz, THD= 10%, RL=2); (3)POUT(2) =26W /channel(VCC=13.2V, f=1kHz, THD= 10%, RL=2); (4)POUT(3)= 19w /chann(VCC=13.2V, f=1kHz, THD= 10%, RL=2); (5)low distortion ratio: THD=0.04% (VCC=13.2V, f=1kHz, POUT=1W, RL=4, GV=50dB); (6)low noise: VNO=0.30mVrms(typ)(VCC=13.2V, RL=4, GV=50dB, Rg =0, BW=20Hz~20kHz); (7)built-in stand-by function (with pin set at low, power is turned OFF.): ISB=100A (TYP); (8)built-in muting function (with pin4 set at low, power is turned OFF.); (9)built-in various protection circuits protection circuits: thermal shut down, over voltage, Out->VCC short, Out->GND Short and OUT- OUT short; (10)operating supply voltage: VCC(opr)=9~18V.

The absolute maximum ratings of TA8221AH 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) impeak): 9A; (5)power dissipation PD: 50W; (6)operating temperature Topr: -30~85°C; (7)storage temperature Tstg: - 55~150°C.
