TA8270HQ

TA8270HQ TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8270HQ Max Power 43 W BTL × 4 ch High Efficiency Audio Power IC The TA8270HQ is TOSHIBA original class KB (Keyed BTL) high efficiency audio amplifier for car audio applications. The Class KB solutions is no need an external LPF for EMI rejection and then it is possible to design for limited small DIN size chassis. Conversely, the class D must need an external LPF. Power dissipation of class KB is no more than a half of the class AB solutions. Therefore, it is possible to design a smaller heatsink and keep lower internal temperature into the car audio set; internal cassette part, CD/MD part etc. Weight: 7.7 g (typ.) This IC can generate more high power and high quality sounds as it is included the pure complementary PNP and NPN transistor output stage. Additionally, stand-by function, mute function, various kind of protector and diagnosis function included output offset voltage detection for car audio use are built-in. 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 = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT (1) = 28 W (typ.) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω) : POUT (2) = 24 W (typ.) (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω) Built-in diagnosis circuit (pin 25) Low distortion ratio: THD = 0.04% (typ.) (VCC = 13.2 V, f = 1 kHz, POUT = 2 W, RL = 4 Ω) Low noise: VNO = 0.13 mVrms (typ....
