Hello everyone,

I am trying to identify an unknown IC and find its correct datasheet. I have clear images of the IC marking/logo, but I have not been able to determine the exact manufacturer and part number.

I suspect it may be from an IC/component manufacturer, but I cannot find a matching part number from the available markings.

I have attached clear images of the IC, including the top marking and package.

Could anyone please help me identify:

• IC manufacturer
• Exact part number
• Datasheet or reference document
• IC function/application, if known
• Any equivalent or compatible part, if available

Any help in identifying this component would be greatly appreciated.

Thank you!

What gear is it from ?
have you looked for a service manual or at minimum, a schematic, of that piece of gear ?

I dont recognise any of the parts of the numbering in the IC
It may possibly be an in-house IC .... that is, manufactured specifically for that company
and info will not be available

As above, what is it from?.
922 is an STmicro dual opamp although the logo on the IC doesn’t seem like it.
Do a photo search of the IC logo to at least find the manufacturer if possible.
