TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8272HQ Max Power 43 W BTL × 4 ch Audio Power IC The TA8272HQ is 4 ch BTL audio power amplifier for car audio application. This IC can generate more high power: POUTMAX = 43 W as it is included the pure complementary PNP and NPN transistor output stage. It is designed low distortion ratio for 4 ch BTL audio power amplifier, built-in stand-by function, muting function, and diagnosis circuit which can detect output to VCC/GND short, output offset voltage and over voltage input mode. Additionally, the AUX amplifier and various kind of protector for car audio use is built-in. Weight: 7.7 g (typ.) Features • High power : POUTMAX (1) = 43 W (typ.) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUTMAX (2) = 40 W (typ.) (VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT (1) = 28 W (typ.) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω) : POUT (2) = 24 W (typ.) (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω) • Built-in diagnosis circuit (pin 25) • Low distortion ratio: THD = 0.02% (typ.) (VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω) • Low noise: VNO = 0.10 mVrms (typ.) (VCC = 13.2 V, Rg = 0 Ω, GV = 26dB, BW = 20 Hz~20 kHz) • Built-in stand-by switch function (pin 4) • Built-in muting function (pin 22) • Built-in AUX amplifier from single input to 4 channels output (pin 16) • Built-in various protection circuit : Thermal shut down, over voltage, out to GND, out to VCC, out to out short • Operating supply voltage: VCC (opr) = 9~18 V Note 1: Install the product correctly. Otherwise, it may result in break down, damage and/or degradation to the product or equipment. Note 2: These protection functions are intended to avoid some output short circuits or other abnormal conditions temporarily. These protect functions do not warrant to prevent the IC from being damaged. - In case of the product would be operated with exceeded guaranteed operating ranges, these protection features may not operate and some output short circuits may result in the IC being damaged.
