The RC4580 is a dual operational amplifier that has been designed optimally for audio applications, such as improving tone control. It offers low noise, high gain bandwidth, low harmonic distortion, and high output current, all of which make the device ideally suited for audio electronics, such as audio preamplifiers and active filters, as well as industrial measurement equipment. When high output current is required, the RC4580 also can be used as a headphone amplifier.
RC4580为音调控制等音响应用而优化设计的双运放,具有低噪声、高增益带宽、低谐波失真、大输出电流等特点,是音响中的理想器件,如前级放大、有源滤波,也可用于仪器仪表。如果需要大电流,也可以当耳机放大器使用。 |
