AD7910/AD7920
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
AD7910/AD7920 feature 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 those listed in the operational sections
of this specification is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.
2
Transient currents of up to 100 mA will not cause SCR latch-up.

NOTES
1
Linearity error refers to integral nonlinearity.
2
KS = SC70, RM = MSOP.
3
This can be used as a stand-alone evaluation board or in conjunction with the EVAL-CONTROL BRD2 for evaluation/demonstration purposes.
4
This board is a complete unit that allows a PC to control and communicate with all Analog Devices evaluation boards ending in the CB designator. To order a
complete evaluation kit, a particular ADC evaluation board must be ordered, e.g., EVAL-AD7920CB, the EVAL-CONTROL BRD2, and a 12 V ac transformer.
See relevant evaluation board technical note for more information.
