TOSHIBA Bipolar Linear Integrated Circuit
Silicon Monolithic
TA8277HQ
Max Power 43 W BTL
× 4 ch Audio Power IC
The TA8277HQ 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 and muting function.
Additionally, the AUX amplifier and various kind of protector
for car audio use is built-in.
Features
High power : POUTMAX (1) = 43 W (typ.)
(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 )
: POUTMAX (2) = 40 W (typ.)
(VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 )
: POUT (1) = 28 W (typ.)
(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 )
: POUT (2) = 24 W (typ.)
(VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 )
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 = 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.
Weight: 7.7 g (typ.)
