Overview
TA8233BH TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8233BH 30W BTL × 2ch Audio Power Amplifier The thermal resistance θj−T 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 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.
