TA8225HQ,TA8225LQ
45W BTL Audio Amplifier
The TA8225HQ, TA8225LQ 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 SW.
In addition, the functions of output short or over voltage
detection and junction temperature are involved.
