The RC4558 device is a dual general-purpose operational amplifier. The combination of the wide supply voltage range (10V to 30V), low noise (6.5nV/√Hz), and distortion performance (0.0001% THD+N) of the device allow the RC4558 to be used in various audio applications. The high common-mode input voltage range and the absence of latch-up of the device are designed for voltage-follower applications. The internal frequency compensation of the device allows for stability without external components.
