TA8276HQ2004-05-101TOSHIBA Bipolar Linear Integrated CircuitSilicon MonolithicTA8276HQMax Power 35 W BTL × 4 ch Audio Power ICThe TA8276HQ is 4 ch BTL audio power amplifier for car audioapplication.This IC can generate more high power: POUTMAX = 35 W as itis included the pure complementary PNP and NPN transistoroutput stage.It is designed low distortion ratio for 4 ch BTL audio poweramplifier, built-in stand-by function, muting function, outputclipping detection and diagnosis circuit which can detect outputto VCC/GND short and over voltage input mode.Additionally, the AUX amplifier and various kind of protectorfor car audio use are built-in.Features• High power : POUTMAX (1) = 35 W (typ.)(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω): POUTMAX (2) = 31 W (typ.)(VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω): POUT (1) = 23 W (typ.)(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω): POUT (2) = 20 W (typ.)(VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω)• Built-in output clipping detection and 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.)1.(VCC = 13.2 V, Rg = 0 Ω, GV = 26 dB, BW = 20 Hz~20 kHz)• Built-in stand-by switch (pin 4)• Built-in muting function (pin 22)• Built-in AUX amplifier from single input to 2 channels output (pin 16)• Built-in various protection circuit: Thermal shut down, over voltage, out to GND, out to VCC, out to out short, speaker burned• Operating supply voltage: VCC (opr) = 9~18 VNote 1: Install the product correctly. Otherwise, it may result in break down, damage and/or degradation to theproduct or equipment.Note 2: These protection functions are intended to avoid some output short circuits or other abnormal conditionstemporarily. 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, theseprotection features may not operate and some output short circuits may result in the IC beingdamaged.Weight: 7.7 g (typ.)
