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.
Linearity error here refers to integral linearity error.
RQ = 0.15" Quarter Size Outline Package.
This can be used as a stand-alone evaluation board or in conjunction with the EVALUATION BOARD CONTROLLER for evaluation/demonstration purposes.
This 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.
