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.
