4 / 24 page REV. PrJ PRELIMINARY TECHNICAL DATA –4– AD7450 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. WARNING!

This board is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards ending in the CB designators. 4S0 = SOIC; RM = µSOIC NOTES 1Stresses 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. 2Transient currents of up to 100 mA will not cause SCR latch up. Figure 1.
