Texas Instruments Changes the NE5532 and Others into Incompatible Versions
Texas Instruments has made significant changes to the NE5532 op-amp, rendering it incompatible with its original version. The modifications include a new manufacturing process and altered specifications, despite retaining the same part number. This has raised concerns among users about sourcing reliable components for older devices.
- ▪Texas Instruments has overhauled the NE5532 op-amp, making it incompatible with the original version.
- ▪The changes include a reduction in supply voltage and a decrease in ESD protection.
- ▪TI also modified other op-amps like the OPA134 and LMH6518, leading to compatibility issues.

Texas Instruments Changes The NE5532 And Others Into Incompatible Versions 1 Comment by: Maya Posch June 3, 2026 Title: Copy Short Link: Copy Texas Instruments SA5532A variant of the 5532 op-amp. (Credit: Raimond Spekking, Wikimedia) First introduced in 1979 by Signetics, the NE5532 was a pretty spiffy dual op-amp for the time with low noise and low distortion. Over the years it has become a standard part that showed up in countless audio products, and has become a so-called jellybean generic component with Texas Instruments (TI) being one of countless manufacturers. It being such a standard, multi-sourced part makes it thus even more puzzling that TI has now decided to completely overhaul this IC in a way that makes it incompatible with even the original Signetics NE5532.
