Product Summary

The TA8273H is a 4 ch BTL audio power amplifier for car audio application. This IC can generate more high power: POUTMAX = 47 W as it is included the pure complementary PNP and NPN transistor output stage. The TA8273H is designed low distortion ratio for 4 ch BTL audio power amplifier, built-in stand-by function, muting function, and diagnosis circuit which can detect output to VCC/GND short, output offset voltage and over voltage input mode.

Parametrics

TA8273H absolute maximum ratings: (1)Peak supply voltage (0.2 s)VCC (surge): 50 V; (2)DC supply voltage VCC (DC): 25 V; (3)Operating supply voltage VCC (opr): 16 V; (4)Output current (peak)IO (peak): 9 A; (5)Power dissipation PD: 125 W; (6)Operating temperature Topr: -40 to 85 °C; (7)Storage temperature Tstg: -55 to 150 °C.

Features

TA8273H features: (1)Built-in diagnosis circuit (pin 25); (2)Low distortion ratio: THD = 0.02% (typ.)(VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4Ω); (3)Low noise: VNO = 0.10 mVrms (typ.)(VCC = 13.2 V, Rg = 0 Ω, GV = 27dB, BW = 20Hz to 20 kHz); (4)Built-in stand-by switch function (pin 4); (5)Built-in muting function (pin 22); (6)Built-in AUX amplifier from single input to 4 channels output (pin 16); (7)Built-in various protection circuit: Thermal shut down, over voltage, out to GND, out to VCC, out to out short; (8)Operating supply voltage: VCC (opr)= 9~16 V.
