TA8220HQ
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8220HQ
30W BTL × 2ch Audio Power Amplifier
The thermal resistance
θj−T
of TA8220HQ package designed for
low thermal resistance, has 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 output short detection circuit,
output clip detection and various kind of protection.
