APPLICATIONS INFORMATION

MOUNTING BEST PRACTICES

For the best performance, follow these rules when installing the

ADIS16486 into a system:

•

Eliminate the opportunity for translational force (x-axis

and y-axis direction, per Figure 18) application on the

electrical connector.

•

Isolate the mounting force to the four corners on the

portion of the package surface that surrounds the

mounting holes.

•

Use uniform mounting forces on all four corners. The

suggested torque setting is 40 inch ounces (0.285 Nm).

These three rules help prevent irregular force profiles that can

warp the package and introduce bias errors in the sensors.

Figure 33 provides an example that leverages washers to set the

package off the mounting surface and uses 2.85 mm passthrough

holes and backside washers and nuts for attachment. Figure 31

and Figure 32 provide details for mounting hole and connector

alignment pin drill locations.

For more information on mounting the ADIS16486, see the

AN-1295 Application Note.
