TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8233BH
30W BTL Ã 2ch Audio Power Amplifier
TA8233BH
The thermal resistance θjâT of TA8233BH 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
builtâin 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.
