Stresses greater than those listed above may cause permanent damage to the
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 ADSP-2191M 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 perfor-
mance degradation or loss of functionality.
