NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational section
of this specification is not implied. Exposure to Absolute Maximum Ratings for
extended periods may affect device reliability.

Negative Input Summing Node
Voltage applied to this pin sets the
common-mode output voltage with a
ratio of 1:1. For example, 1 V dc on
V
OCM
will set the dc bias level on +OUT
and –OUT to 1 V.
Positive Supply Voltage
Positive Output. Note that the voltage at

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
AD8138 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.
