PRELIMINARY TECHNICAL DATA ADMC328
–5–
REV. A
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 ADMC 328 features proprietary ESD protection circuitry,
permanent damage may occur on devices subjected to high energy electrostatic dis-
charges. T herefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
