Overview
The RC4558PWRG4, produced by Texas Instruments, is a dual general-purpose operational amplifier. This device is part of the RC4558 family and is packaged in a TSSOP (Thin Shrink Small Outline Package) with 8 pins. The RC4558 is designed to offer a wide supply voltage range, low noise, and excellent distortion performance, making it suitable for various audio and industrial applications.
The device features internal frequency compensation, which ensures stability without the need for external components. It also has a high common-mode input voltage range and is free from latch-up, making it ideal for voltage-follower applications.
