20W BTL × 2ch Audio Power Amplifier
TA8210AHQ
The thermal resistance θj−T of TA8210AHQ, TA8210ALQ 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.
