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 o
