Overview
The RC4558PWRE4 is a dual general-purpose operational amplifier produced by Texas Instruments. This device is part of the RC4558 series and is packaged in an 8-TSSOP (0.173", 4.40mm Width) package. The RC4558 is known for its wide supply voltage range (10V to 30V), low noise (6.5nV/√Hz), and low distortion performance (0.0001% THD+N), making it suitable for various audio applications. The internal frequency compensation ensures stability without the need for external components, and the device features continuous short-circuit protection and no latch-up, which are beneficial for voltage-follower applications.
