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 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.

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 listed in the operational section of this
specification is not implied. Exposure to Absolute Maximum Ratings for any
extended periods may affect device reliability.
2 Thermal resistance measured on SEMI standard 4-layer board.

1
–IN
Negative Input Summing Node.
2VOCM
Voltage applied to this pin sets the common-
mode output voltage with a ratio of 1:1. For
example, +1 V dc on VOCM will set the dc
bias level on +OUT and –OUT to +1 V.
3
V+
Positive Supply Voltage.
4
+OUT
Positive Output. Note: the voltage at –DIN is
inverted at +OUT.
5
–OUT
Negative Output. Note: the voltage at +DIN
is inverted at –OUT.
6
