That SEEMS like the right answer but an NE5532 is an 8-pin op amp device and the OP's photo is a 16-pin device.Delete the 'D', then search.
Welcome to AAC!
Thank you for the help. That’s flux on top of the chip.That SEEMS like the right answer but an NE5532 is an 8-pin op amp device and the OP's photo is a 16-pin device.
Also, the OP's chip appears to have been abraded with sandpaper or sandblasting and stamped over the roughened area. The chip has flux on it. It’s not abraided
It’s an SMPS controller, not an opamp. The “S” is the Signetics logo. Philips owns or owned them. Some of the “NE5532D”s have the Philips logo. You can buy these on eBay and AliX. Philips does offer an NE5560 SMPS controller in an SOP-16.Since the package appears to be a fake and "S" company is not a Name-Brand then a good NE5532D dual opamp should be found as a replacement and used.

Do you want a stack? I have some original NE555, NE5532 and NE5534 if you want some.I agree and forgot that the NE5532 dual opamp in this thread was designed many years ago by Signetics who also designed the NE555 timer. I worked for Philips when they bought Signetics 47 years ago but I have never seen an antique Signetics IC.
Because of this. If you search for NE5532D on AliXpress you will find other sellers as well. I know it's very strange but apparently someone is producing a (probably bogus) version of the Signetics/Philips NE55xx SMPS controller with that number. You can find the OPA as well, though only in SOP-8.
Who ya gunna trust - a Signetics/Philips datasheet or Chinese ebay seller?I'll add that it is certainly possible that these sellers got the nature of the part wrong and it really is an OPA, but these are the only examples of the SOP-16 package and they are all marked "voltage regulator" in specifications. There is one that has "switching power supply" in the description.
