There is no notch on ADE7757arn how am i gonna determine the pins?
Check to see if one side edge of the chip is sloping. Then orient the chip such that the sloping edge is on the left side. The top left pin would be the pin 1.
Let me know if this works out fine.
Can you elaborate your query? The pin out for the chip looks like this:
Do you mean you aren't able to locate pin 1 of the chip correctly?
Actually i have bought the IC but there is no notch on the IC. I am attaching the picture. can you guide me where is pin 1 located?
The chip image seems different. Kindly confirm if you see a small dot identifying the pin1 of the chip, as seen in the pin configuration image that I had attached in my previous post.
Also, can you let us know the source through which you had bought this chip?
There is no notch on the IC, just the logo of ANALOG DEVICES.. The IC is SMD Narrow body type.
I bought it from the following link
I would recommend you to contact a local distributor to buy ADE7757 ICs:
or buy them directly from ADI’s website.
Do you think you can do that before continuing to evaluate and use ADE7757 IC?
I cannot buy directly from ADI's website because they do not provide shipping for my country. I have to buy it from Hong Kong which takes about a month to reach my location.
Thanks a lot for the other link that you provided. I have been able to successfully locate the sloping and pin 1.
