NOTES
1Stresses 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. Only one Absolute
Maximum Rating may be applied at any time.
2The outputs may be shorted to voltages in this range provided the power dissipation
of the package is not exceeded. Short circuit current is typically 80 mA.
(VDD = +10.8 V to +16.5 V, VSS = 0 V or –10.8 V to –16.5 V, AGND = DGND = 0 V,
RL = 2 k , CL = 100 pF. All Specifications TMIN to TMAX unless otherwise noted.)
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 AD7243 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!
