XL4558 – Operational Amplifier – Xinluda

The XL4558 from Xinluda is a dual general-purpose operational amplifier in an SOP-8 package, offering 3 MHz unity-gain bandwidth, internal frequency compensation, and continuous output short-circuit protection. Available by RFQ from Pacific Component Xchange.

The XL4558 is a dual general-purpose operational amplifier manufactured by Xinluda, with each amplifier section offering electrical performance comparable to industry-standard 4558-class devices. The design provides a wide common-mode and differential input voltage range, internal frequency compensation that eliminates the need for external components, and continuous output short-circuit protection. The DIP-8 variant of this device is designated XD4558, while the surface-mount SOP-8 version carries the XL4558 part number.

With its 3 MHz typical unity-gain bandwidth and low input-referred noise, the XL4558 is well suited to audio signal conditioning and general analog applications where a robust, cost-effective dual op-amp is required. It is a functional alternative to common LM4558/RC4558-style devices.
