AD9480 ABSOLUTE MAXIMUM RATINGS
Thermal impedance (θJA) = 46.4°C/W (4-layer PCB).
Table 5. Parameter Min Rating Max Rating
Stresses above those listed under Absolute Maximum Ratings ELECTRICAL may cause permanent damage to the device. This is a stress AVDD −0.5 V +4.0 V rating only; functional operation of the device at these or any (With Respect to AGND) other conditions above those indicated in the operational DRVDD −0.5 V +4.0 V section of this specification is not implied. Exposure to absolute (With Respect to DRGND) maximum rating conditions for extended periods may affect AGND −0.5 V +0.5 V (With Respect to DRGND) device reliability. Digital I/O −0.5 V DRVDD + 0.5 V (With Respect to DRGND) Analog Inputs −0.5 V AVDD + 0.5 V (With Respect to AGND) ENVIRONMENTAL Operating Temperature −40°C 85°C Junction Temperature 150°C Case Temperature 150°C Storage Temperature 150°C
EXPLANATION OF TEST LEVELS Table 6. Level Descriptions
I 100% production tested. II 100% production tested at 25°C and guaranteed by design and characterization at specified temperatures. III Sample tested only. IV Parameter is guaranteed by design and characterization testing. V Parameter is a typical value only. VI 100% production tested at 25°C and guaranteed by design and characterization for industrial temperature range.
ESD 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 this product 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. Rev.
