Smd component identification.

[satanistik]

I need to identification SMD X8TA SOT23 ic from movi gimbal board. I think it's single opamp or logic gate.

No picture, don't even tell how many pins it has? 

[satanistik]

I have board in my workshop, its 5 pin and I can measure gng and vcc pin.

Not sure but looks close to this one:

[R-1125F]

Please post a photo of your board.

Some photos.

This PCB is a bit weird. I mean the designators of those chips. How come some are prefixed with IC and others are prefixed with U?

Lmv331 don't have this mark code in pdf. I think it's comparator or aperation amplifier. But out is connection to ground width resistor and this not look to open collector.

What are talking about? Did you really read the data sheet carefully?

[satanistik]

From pdf - open collector output.

and? A pull-down resistor doesn't tell anything, it's most likely being pulled up elsewhere.

- Yes, its fact - board have multi layers and making schematic are dificult.
I have second ic on this board looking good, first have broken pin. I try to make test circuit.

Could it be ...

U = analogue
IC = digital

Yeah, nah, the IC1 is a TJA1051 high speed CAN transceiver, but the IC2 is an AP2210N-3.0 LDO.
