Ic chips: 2 pcs TA8271H max power 41W 4 ch audio power
- The TA8271H 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 and muting function.
-Additionally, the AUX amplifier and various kind of protector for car audio use is built-in.
- High power : POUTMAX (1) = 41 W (typ.)(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 OHM)
: POUTMAX (2) = 37 W (typ.)(VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 OHM)
: POUT (1) = 24 W (typ.)(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 OHM)
: POUT (2) = 21 W (typ.)(VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 OHM)
- Low distortion ratio: THD = 0.02% (typ.)(VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 OHM)
- Low noise: VNO = 0.18 mVrms (typ.)(VCC = 13.2 V, Rg = 0 OHM, GV = 34dB, 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 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
- Operating supply voltage: VCC (opr) = 9~18 V
