The RC4580 device 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 preamplifiers, active filters, and industrial measurement equipment. When high output current is required, the RC4580 device can be used as a headphone amplifier. Due to its wide operating supply voltage, the RC4580 device can also be used in low-voltage applications. Drop-In Replacement for NJM4580 Pin and Function Compatible with LM833, NE5532, NJM4558, NJM4559, NJM4560, NJM4562 and NJM4565 devices.
