Unable to judge the correct pin configuration of OPA333

[patan.gova]

Hello,
I got an OPAMP sample with 8-pins from TexasInstrument labelled on the package as "OPA333AID" and DESC: IC OPAMP 8-SOIC (The datasheet is attached below) .On the OPAMP chip I got is lablelled as "O333A35K C651G4" and there is no point on the chip that actually indicates the pin1 as it is actually shows in the datasheet.

Can I follow the pin configuration of this opamp as same as shown in the page5 as "D PACKAGE SO-8 (TOPVIEW)"?
Can someone help in finding the pin1 to pin8 of this?
thanks.

there is no point on the chip that actually indicates the pin1

Even then there should be a chamfered edge which indicates the position of pin 1 :

Hi erikl,
No,the OPAMP doesnt have the indicator shown in both the images but it has something like this **broken link removed**

Can I know how to proceed ?

Nothing to be seen. "Invalid Attachment specified."

Hi,

Here it is

Then I'd think this bar marks pins 1 & 8 , s. here: .

Be careful anyway: for the 1^st trial I'd suggest to limit/measure the power supply current.

Even without any marks the text orientation still indicates pin 1 bottom-left.
