OP-amp's pin 1 (OPA2365)

The actual package's photos are attached.

I doesn't have the dot or the round cutout.

Am I correct that the vertical line is marking the cutout side and pin 1 is on the bottom left in my top view photo?

It is kind of confirmed by the chamfer on the bottom corresponding to the drawing in the datasheet, but I'm not 100% sure.

Is one side of the package cut/chamfered at 45 degrees? It's a bit hard to tell from the pictures, but it looks like from the pictures that the bottom side of the text is chamfered at 45 degrees. It's not very common to see and probabably not general knowledge but the chamfered side marks the pin 1 location.

Edit: Duh, you did mention the chamfer. It does indeed mark the pin location.

Yes and yes. The bottom side (on your pic) is definitely chamfered.
