Help identifying quad OP Amp

[CTack.2]

See picture above for exact markings. No markings on the bottom of the IC.

Battery powered device (low voltage)

Markings:

ST (e3) 7B589

VA1814

PHL 423

Alternate version has similar markings. Maybe just a date code change?

ST (e3) 7B474

VA1814

PHL 423

My money is an ST second-source/equivalent to the LT1814

@Community member​ is not completely right, it is the TSZ124IPT with marking VA1814.

I can't be right all the time, but it helps significantly if the markings match what's in the documentation, and the documentation with the markings is spidered by Google.

If your web-devs are searching for productive tasks not involving just changing/fiddling the look/feel of the web portal, might I suggest some part#/marking search index that can help narrow parts from the past/present, along with suggested ordering numbers, or replacement/substitute parts. Bonus points for lead time information, estimated EOL date and 10-20-30 year availability status.
