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.
The XL4558 is a hard-to-find part with little or no authorized-distributor stock. Pacific Component Xchange specializes in sourcing scarce, end-of-life, and allocation-constrained components like the XL4558 for engineers and procurement teams worldwide. Every order is backed by our authenticity and quality-assurance process to protect your build against counterfeit risk, and we ship globally with flexible quantities. Submit an RFQ for the XL4558 today and our sourcing specialists will respond with current availability, lead time, and pricing.
The XL4558 is a dual general-purpose operational amplifier from Xinluda, not a DC-DC converter. The similarly named XL4015 is the Xinluda buck converter; the XL4558 is an analog amplifier in the 4558/LM4558 family.
They are the same op-amp die in different packages. The XL4558 is the surface-mount SOP-8 version, while the XD4558 is the through-hole DIP-8 version, as stated in the manufacturer datasheet.
The XL4558 is a 4558-class dual general-purpose op-amp and is commonly used as a functional alternative to LM4558/RC4558 devices. Always verify pinout and electrical parameters against your circuit requirements before substituting.
The XL4558 is supplied in an 8-pin SOP-8 surface-mount package. A DIP-8 through-hole equivalent is offered under the XD4558 part number.
Yes. The XL4558 has limited authorized-distributor availability. Pacific Component Xchange specializes in sourcing hard-to-find components like this and can provide a quote with current lead time and authenticity assurance upon RFQ.
The XL4558 operates over a commercial temperature range of 0u00b0C to 70u00b0C per the manufacturer datasheet.
