So it should be the chip that powers the op amp. 258 and 224 are op amps. You can find the power and ground pins in the chip manuals of 258 and 224, and then check and judge according to the silk screen circuit. If it is determined to be a power supply chip, you can find a replacement chip.

It was removed from that functional board.

Looks like an optocoupler.

OK, thank you

I checked these functions and none of them are suitable. This one should be a device that provides reference voltage

I took a general look at MAX6023. The functions are somewhat similar, but the package is wrong and other functions are not suitable. This model should be used to provide reference voltage.
