Max Power 41 W BTL × 4 ch Audio Power IC
The TA8275HQ is 4 ch BTL audio power amplifier for car audio
application.
This IC can generate more high power: POUTMAX = 41 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) = 41 W (typ.)
(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 )
: POUTMAX (2) = 37 W (typ.)
(VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 )
: POUT (1) = 24 W (typ.)
(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 )
: POUT (2) = 21 W (typ.)
(VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 )
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 )
Low noise: VNO = 0.10 mVrms (typ.)
(VCC = 13.2 V, Rg = 0 , 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.
