NOTES

1Stresses 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.

2Transient currents of up to 100 mA will not cause SCR latch up.

Specifications

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.
