<![CDATA[Fake audio opamp - Ti NE5532 remarked as AD OP275 : weekend die-shot]]> http://zeptobars.com/en/read/fake-op275-analog-devices-ad-NE5532-Ti-audio-opamp-remarked Ti NE5532 die. As it was quite unusual, I de-capped original Ti NE5532 (directly from their e-shop) to confirm that older photo was indeed from genuine part, as well as one more fake OP275 to confirm that there was no mistake.

It looks like someone remarked Ti NE5532 as Analog Devices OP275. Die attach and properties of plastic package also suggest Ti origin of this part.

<![CDATA[Fake CD40106B CMOS Hex Schmitt-Triggers Inverters : weekend die-shot]]> http://zeptobars.com/en/read/CD40106B-CMOS-Hex-Schmitt-Triggers-Inverters-fake-ebay-Ti-texas-instruments CD4049 (hex inverter) we've decapped earlier : transistors needed for Schmitt-input were also present at CD4049, but not connected by different top metal. Somebody did saved few thousands $ here.

Die size 714x849 µm.

Update: Now with metal stripped. it's a metal-gate CMOS, so no gates survived:
