TA8215H / L
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8215H,TA8215L
18W BTL x 2CH Audio Power Amplifier
The thermal resistance θj−T of TA8215H and TA8215L 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.
