Overview
The RC4558P is a dual general-purpose operational amplifier produced by Texas Instruments. It is designed to be versatile and suitable for various audio and industrial applications. The device is electrically comparable to the μA741, except for the absence of offset null capabilities. The RC4558P features a wide supply voltage range of 10V to 30V, low noise of 6.5nV/√Hz, and excellent distortion performance of 0.0001% THD+N. These characteristics make it ideal for voltage-follower applications and other scenarios requiring high common-mode input voltage ranges and stability without external frequency compensation.
