TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8271H
Max Power 41 W BTL × 4 ch Audio Power IC
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.
Features
· High power: POUTMAX (1) = 41 W (typ.) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUTMAX (2) = 37 W (typ.) (VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT (1) = 24 W (typ.) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω) : POUT (2) = 21 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 = 0.18 mVrms (typ.) (VCC = 13.2 V, Rg = 0 Ω, GV = 34dB, BW = 20 Hz~20 kHz) Built-in stand-by switch function (pin 4) Built-in muting function (pin 22)
Weight: 7.7 g (typ.)
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
