AD7450A/AD7440
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 AD7450A/AD7440 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.

NOTES
1
Stresses above those listed under “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 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.
2
Transient currents of up to 100 mA will not cause SCR latch up.

This can be used as a stand-alone evaluation board or in conjunction with the EVALUATION BOARD CONTROLLER for evaluation/demonstration purposes.
3
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.
TBD, the EVAL-CONTROL BRD2 and a 12V AC transformer. See the TBD technote for more information.
