Overview
TA8205AH / AL TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8205AH,TA8205AL 18W BTL × 2CH Audio Power Amplifier The thermal resistance θj−T of TA8205AH, TA8205AL 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.
This stereo audio power IC, designed for car audio use, has two built−in channels to reduce the characteristic difference between L and R channels.
In addition, the functions of stand−by and muting, and a variety of protection circuits are involved.
