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.)
(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
Weight: 7.7 g (typ.)
