... TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8221AHQ,TA8221ALQ 30W BTL × 2Ch Audio Power Amplifier The thermal resistance θj−T of TA8221AHQ, TA8221ALQ package designed for low thermal resistance, has a high efficiency of heat radiation. The temperature rise of chip can be reduced, and the influence from the degradation of the features due to the temperature rise at the high output can also be reduced ...
