*Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. This is a stress rating only; the functional operation of

the device at these or any other conditions above those indicated in the operational

sections 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 greater than 2000 g

and exceed the absolute maximum rating of the device. Care

should be exercised in handling to avoid damage.

Figure 1 shows the response of the ADXL190 to the earth’s

gravitational field. The output values shown are nominal. They

are presented to show the user what type of response to expect

from each of the output pins due to changes in orientation with

respect to the earth.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection.

Although the ADXL190 features proprietary ESD protection circuitry, permanent damage may

occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD

precautions are recommended to avoid performance degradation or loss of functionality.

WARNING!
