Help identify IC in Rigol DP832

[giosif]

Hello,

I am currently working on fixing the board for CH1 from a Rigol DP832 power supply and, amongst other things, I am trying to identify some of the components that had their markings lasered off by the manufacturer (thanks, Rigol!).
One of these components is U14 and, looking at it closely, I noticed that, if held in the sunlight and looked at from the right angle, one can just about see traces of the original markings.
I took some photos of the IC from the best angles I could determine and included them here - https://flic.kr/ps/3UHswc
Does anyone recognize the markings and the actual IC make and model?

Thanks!

One could have at least rotated to picture the right way to make reading more easy. Looks like the date code is readable 1412, but the interesting part not really.

I think you need to work with it a bit more.
Pictures and videos are lucky guesses.
My first thought was that it's an ASIC chip but then why bother hiding your own numbers.

Dave's pictures have a chip where smearing is not straight.
There top left could be a logo or a part of it.

Last line could be 630-8411.1
Post number in Nara, Japan?

Get a stobe light a bit off from camera sync and a polarisation raster film plate.
Light up, put the plate over the chip, look the picture through the camera and pick your angle.
Having intensity adjusting trigger is not bad.
Maybe a bit less is enough.

In case you are sensitive, have a puke bucket nearby and don't be going anywhere shortly afterwards.

Fair enough.
I've rotated the pictures and uploaded them - https://flic.kr/s/aHsmS1ckNB
Indeed, the most important part is difficult to read, but this was the angle which was revealing the markings the best.

Thank you for the suggestion!
This is certainly interesting, but I am not equipped with the required tools, so I'm afraid I will not be implementing it.

One top left of Dave's pictures has a clear dot.
Infineon has a dot but this is too big.
It's also solid so not ie. Microchip or the likes with decorated dot.

Next line starts with E or B.
Next with D.

Same set of Dave's have different numbers at the bottom.
Probably some production number then and pretty useless.

Impressive! 
I think you are right on the money.
It matches at least part of the pinout (i.e. whatever pins for which I could determine their function on my CH1 board), and the markings seem to fit whatever I can make out from my photos, as well as whatever is visible in Dave's photo.
Hmmm... What's the next step, I wonder...

Better that way, there must be easier ways for video effects.
And polaroid was a wrong word, raster is the right one.

End of second row doesn't fit.
AD has normal and mass order types.
Last of the 2nd row of the smeared one could be 7 and mass order type has a suffix as -R7.
Six characters of 2nd row could be BCPZR7.

Actually, you are right.
Looking at this a bit more, I am 99% sure it is a ADuC7060BCPZ32 instead.

My first guess for the 2nd row was [B/E]*-Z3[2/7] but after gamalot's post that last digit started to look like a clear 7.
1st row ending was guessed as /0[6/G] and empty space before it, where now is a clear low hook.
Everything fits.
And BTW, what TurboTom said.
