TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA7280P,TA7281P
5.8W Dual Audio Power Amplifier. 22W BTL Audio Power Amplifier.
The TA7280P, TA7281P are dual audio power amplifier for consumer applications. It is designed for high power, low distortion and low noise. It also contains various kind of protectors. It is suitable for car−audio power amplifier with high performance. The kinds of pin configuration are available: Normal (TA7280P) and reverse (TA7281P) for easier layout design of PC−board when used in BTL−stereo application.
