are measured from the 1.5 V level of the ENCODE to the 10%/90% levels of the digital output swing. The digital output load during test is not to exceed
an ac load of 10 pF or a dc current of ± 40 µA.

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
AD9059 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.
