NOTES
1
Linearity error here refers to integral linearity error.
2
N = Plastic DIP; R = SOIC; RS = SSOP.
3
L signifies the low-power version.
4
This can be used as a stand-alone evaluation board or in conjunction with the EVAL-
CONTROL BOARD for evaluation/demonstration purposes.
5
This board is a complete unit allowing a PC to control and communicate with all
Analog Devices evaluation boards ending in the CB designators.

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
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
2
Transient currents of up to 100 mA will not cause SCR latch-up.

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 AD7858/AD7858L 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.
WARNING!
