TA8215H

The thermal resistance j-T of TA8215H package 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. In addition, the functions of stand-by and muting, and a variety of protection circuits are involved. 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 TA8215H can be summarized as (1)high power: POU1-(1) =18W(Typ.)/Channel (VCC=14.4V, f=1kHz, THD=10%, RL=4):POUT-(2) =15W(Typ.)/Channel (VCC=13.2V, f=1kHZ, THD=10%, RL=4); (2)low distortion ratio: THD=0.04%(typ.)(VCC=13.2V, f=1kHz, POUT=1W, RL=4, GV=50dB); (3)low noise: VNO =0.30mVrms(VCC=13.2V, RL=4, GV=50dB, Rg=0, BW=20Hz~20kHz); (4)built-in stand-by function (with pin 4 set at low, power is turned off.): ISB =1A; (5)built-in muting function (with pin 1 set at low, power is turned off.): V(Mute)= 1V; (6)built-in various protection circuits; (7)protection circuits: thermal shut down, over voltage, OUT->VCC short, OUT->GND short and OUT-OUT short; (8)operating supply voltage: =9~18V.

The absolute maximum ratings of TA8215H are (1)peak supply voltag(0.2s) VCC(surge): 50 V; (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.
