EEVblog 1752 – Texas Instruments SCREWED UP the NE5532
WTF were Texas Instruments thinking changing the design and major specs of the 45+ year old jellybean NE5532 audio opamp WITHOUT changing the part number?!
New datasheet: https://www.ti.com/lit/ds/symlink/ne5532.pdf
Old datasheet: https://www.mouser.com/datasheet/2/405/ne5532a-556776.pdf
Change Notification: https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/5726/PCN20231114002.1.pdf
Onsemi datasheet: https://www.onsemi.com/pdf/datasheet/ne5534-d.pdf
Forum thread: https://www.eevblog.com/forum/chat/ti-ne5532-audio-opamp-changes/
OPI134: https://www.ti.com/lit/ds/symlink/opa4134.pdf
00:00 – TI have changed the classic jellybean NE5534
03:27 – Product Change Notifications (PCN’s)
06:43 – List of the changes
09:07 – Don’t worry abut that 600ohm load rubbish
10:45 – Let’s look at other manufacturers
12:50 – The OPA134 has a WILD change!
18:15 – They formally claim the changes have NO IMPACT! This could get them sued…
19:20 – Is the Single NE5534 impacted?
20:30 – This LMH6518 change might be killing oscilloscopes!
23:25 – Here is how it’s done: LM317
