由Burr Brown公司生产的OPA512SM功率放大器具有输出功率大、失真小和耐持久等特点。该集成电路内置有限压、限流保护电路,即使输入电流高达15A(峰值)的情况下,也能正常工作。该集成电路采用TO—3封装,可使内部电路与外封装绝缘。因此,可直接安置于金属底座或散热片上,而不需要绝缘材料。利用该性能,可将该芯片直接安装于一个小巧的金属外壳上。这样,可减小电路板面积。该集成电路广泛应用于重低音放大器、功放系统、电吉它放大器等。该集成电路的输出级工作在甲乙类状态,电路失真小,静态电流也很小。因该电路有限流电路,即使当扬声器的两根导
The OPA512SM power amplifier manufactured by Burr Brown Corporation features high output power, low distortion and long lasting performance. The integrated circuit has a built-in limited voltage, current limiting protection circuit, even if the input current up to 15A (peak) case, but also to work properly. The IC is packaged in TO-3 to insulate the internal circuitry from the package. Therefore, it can be placed directly on the metal base or heat sink, without the need for insulating material. With this feature, the chip can be mounted directly on a small metal case. In this way, the board area can be reduced. The IC is widely used in bass amplifiers, power amplifier systems, electric guitar amplifiers and more. The IC’s output stage in Class A and B states, circuit distortion, quiescent current is also small. Because the circuit has a current-limiting circuit, even when the two conductors of the speaker
