NOTES
1Stresses above those listed under Absolute Maximum Rating may cause permanent
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.
2Transient currents of up to 100 mA will not cause SCR latch-up.

2RQ = 0.15" Quarter Size Outline Package.
3This can be used as a stand-alone evaluation board or in conjunction with the EVALUATION BOARD CONTROLLER for evaluation/demonstration purposes.
4This EVALUATION BOARD CONTROLLER is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards ending in the
CB designators.
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 AD7843 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.
