PIN CONFIGURATION

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 ADXL105 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!

ESD SENSITIVE DEVICE

Drops onto hard surfaces can cause shocks of greater than 1000 g

and exceed the absolute maximum rating of the device. Care should

be exercised in handling to avoid damage.
