Микросхема TA8215L

TA8215L packagedesigned for low thermal resistance, has a high efficiency of heatradiation.The temperature rise of chip can be reduced, and the influencefrom the degradation of the features due to the temperature riseat the high output can also be reduced.This stereo audio power IC, designed for car audio use, has twobuilt−in channels to reduce the characteristic difference betweenL and R channels.In addition, the functions of stand−by and muting, and a varietyof protection circuits are involved.TA8215HFeaturesTA8215L· High power: POUT (1) = 18W (typ.) / channel(VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4Ω): POUT (2) = 15W (typ.) / channel(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4Ω)· Low distortion ratio: THD = 0.04% (typ.)(VCC = 13.2V, f = 1kHz, POUT = 1W, RL = 4Ω, GV =50dB)· Low noiseWeightHZIP17−P−2.00 : 9.8g (typ.)HSIP17−P−2.00 : 9.8g (typ.): VNO = 0.30mVrms (typ.)(VCC = 13.2V, RL = 4Ω, GV 50dB, Rg = 0Ω, BW = 20Hz~20kHz)· Built−in stand−by function (with pin (4) set at low, power is turned off.): ISB = 1µA (typ.)· Built−in muting function (with pin (1) set at low, power is turned off.): V(mute) = 1V (typ.)· Built−in various protection circuitsProtection circuits : Thermal shut down, Over voltage, Out→VCC short, Out→GND short and Out−Outshort.· Operating supply voltage : VCC = 9~18V
