RATE SENSITIVE AXIS
The ADXRS622 is a Z-axis rate-sensing device (also called a
yaw rate-sensing device). It produces a positive going output
voltage for clockwise rotation about the axis normal to the
package top, that is, clockwise when looking down at the
package lid.

Stresses above those listed under the Absolute Maximum
Ratings may cause permanent damage to the device. This is a
stress rating only; functional operation of the device at these or
any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
Drops onto hard surfaces can cause shocks of >2000
g
and can
exceed the absolute maximum rating of the device. Exercise
care during handling to avoid damage.
