TA8215HQ/LQ
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8215HQ,TA8215LQ
18W BTL × 2CH Audio Power Amplifier
The thermal resistance θj−T of TA8215HQ and TA8215LQ
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.
