i need to connect my ADIS16448/PCBZ to my PCB. but i've been asked to know the center point of it. i've searched the datasheet
but i couldn't find it. can u help me with this?
Check out the attached diagram. I have identified the Center of Gravity by the three dimensions. Hope that helps!

Here is a dimension drawing for this boards, which will complement Figure 24 on page 22 of the datasheet. The smaller dimensions match the nominal center of the mounting holes. I would use the outer dimensions to compute the center locations.
the 38.1 is the dimension of the interface board? i'll add this dimension to the cable and adis6448BMLZ dimesion and then caculate
the center ? and based on what the cable dimesion i'll use
My previous post showed the dimensions for the interface board. I am struggling to understand why the "center" is important. Can you help me out with this?
sorry for being late. i need to integrate the output from this ADIS with another EVAL-ADXL345Z and use it in my project.
but to do that..... i have a relation that requires the distance between the centers of the above sensors.
thats why im asking about.
so i also need the center of the EVAL-ADXL345Z if u can help me also
It seems like you are asking for the center of gravity on the ADXL345 so is it same to assume that you are asking for the same thing in this case? If so, can you help me understand how that helps you align the ADIS16448 to the ADXL345? For inertial alignment, the point of percussion might be helpful as well. Please see page 20 of the ADIS16448 datasheet for more information on this. Note that the present revision of the ADIS16448 datasheet is A. After doing some quick tests on this, it appears like the center of gravity is equal to the geometric mean, (using the package lid height, not the mounting ledge height). Hope that helps!
thanks for the reply.....but im not sure what u mean with the package lid height and the mounting ledge height ?
The original PDF file had a mistake in the z-axis dimensional reference. Please see the attachment in this post for the latest information.
One more point of clarification. The graphic files illustrates the COG for the ADIS16448xMLZ, not the ADIS16448/PCBZ.
