Simple, Affordable and Ultra-Reliable 2520 and 990 Op-Amp Solution

The LX5534 is a cost-effective alternative and direct replacement adapter for standard 2520 and 990 discrete operational amplifier sockets. It allows you to drop classic monolithic IC op-amps such as the included NE5534A or the high-performance OPA134 directly into any equipment utilizing a standard 6-pin DOA footprint.

Whether you need a reliable, budget-friendly op-amp to test newly built 500-series modules, want an ultra-low power consumption alternative, or simply prefer the clean, dependable response of iconic IC op-amps, the LX5534 provides a straightforward solution.

With a tiny 28 mm by 28 mm footprint, high-quality gold-plated pins, and low current draw, the LX5534 kit is an essential utility for any audio DIY workbench or custom gear build.
