TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8277H
Max Power 43 W BTL × 4 ch Audio Power IC
The TA8277H 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.)
Weight: 7.7 g (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)
· 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

4. AUX Input (pin 16)
The pin 16 is for input terminal of AUX
amplifier.
The total gain is 0dB by using of AUX amplifier.
Therefore, the m-COM can directly drive the
AUX amplifier.
BEEP sound or voice synthesizer signal can be
input to pin 16 directly.
When AUX function is not used, this pin must be
connected to PRE-GND (pin 13) via a capacitor.
