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.
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.
It also contains various kind of protection.
