From web link @ AD7853LARSZ, we get different two package information.Which is correct ?
From package information link,
I check the details on this but for now we will refer specification from the datasheet.
My mistake. Please follow the dimension from the website.
By the way what type of application the part will be used? What ADC specification that you are looking for. There are newer ADI parts that may also fit the application. We can help look for alternative parts.
