TA8231LQ
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8231LQ
42W BTL × 2CH Audio Power IC
The TA8231LQ is BTL audio power amplifier for consumer
application. It is designed for high power,low distortion and low
noise.
It contains various kind of protectors and the function of
stand−by.
