Overview
The RC4558D, produced by Texas Instruments, is a dual general-purpose operational amplifier designed for a wide range of applications, particularly in the audio and industrial sectors. This device is notable for its wide supply voltage range of 10V to 30V, low noise characteristics (6.5nV/√Hz at 10kHz), and excellent distortion performance (0.0001% THD+N at 1kHz). The RC4558D features internal frequency compensation, eliminating the need for external components for stability, and is free from latch-up, making it suitable for voltage-follower applications.
