Anyone want to guess this IC?
(1/1)
rx8pilot:
Trying to identify a BGA on a Sony monitor PCB. It appears to be in the area that deals with on-board audio, headphones, etc....perhaps an amplifier?


30 Ball BGA
MARKING:

--- Code: ---Y158
239PE
0

--- End code ---

The only thing I could find so far is some random thing on Alibaba - but with no real data on what it is.

Anyone have an idea on this one?

Seems like a good match, what you think?

It appears to be....I traced a number of the pins  - SDA, SCL, GND, etc and they match other parts on the board.

Curious how you found this? What did you search for? Perhaps a part family you are already familiar with?
abraxa:
I searched for "Y158 amplifier", came across the URL amyk posted, figured it could be a YDA158 and googling "YDA158 amplifier" gave the URL to the data sheet.
