TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8272HQ Max Power 43 W BTL × 4 ch Audio Power IC The TA8272HQ 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, muting function, and diagnosis circuit which can detect output to VCC/GND short, output offset voltage and over voltage input mode. Additionally, the AUX amplifier and various kind of protector for car audio use is built-in. Weight: 7.7 g (typ.) Features • High power : POUTMAX (1) = 43 W (typ.) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUTMAX (2) = 40 W (typ.) (VCC [ ... ]
