TA8276HQ

Max Power 35 W BTL × 4 ch Audio Power IC

The TA8276HQ is 4 ch BTL audio power amplifier for car audio

application.

This IC can generate more high power: POUTMAX = 35 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, output

clipping detection and diagnosis circuit which can detect output

to VCC/GND short and over voltage input mode.

Additionally, the AUX amplifier and various kind of protector

for car audio use are built-in.

Weight: 7.7 g (typ.)

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 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.
