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
AD7450 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 nonlinearity error.
SO = SOIC; RM = µSOIC.
This can be used as a standalone evaluation board or in conjunction with the Evaluation Board Controller for evaluation/demonstration purposes.
Evaluation Board Controller. This board is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards
ending in the CB designators. To order a complete evaluation kit, you will need to order the ADC evaluation board, i.e.. EVAL-AD7450CB, the
EVAL-CONTROL BRD2, and a 12 V ac transformer. See the AD7450 evaluation board technical note for more details.

Stresses above those listed under the Absolute Maximum Ratings may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any 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.
Transient currents of up to 100 mA will not cause SCR latch up.
