AD9218 ABSOLUTE MAXIMUM RATINGS EXPLANATION OF TEST LEVELS Table 5. Parameter Rating
I. 100% production tested. VD, VDD 4 V II. 100% production tested at 25°C and sample tested at Analog Inputs –0.5 V to VD + 0.5 V specified temperatures. Digital Inputs –0.5 V to V + 0.5 DD V REFIN Inputs –0.5 V to VD + 0.5 V III. Sample tested only. Digital Output Current 20 mA Operating Temperature –55°C to +125°C IV. Parameter is guaranteed by design and characterization Storage Temperature –65°C to +150°C testing. Maximum Junction Temperature 150°C V. Parameter is a typical value only. Maximum Case Temperature 150°C θA (measured on a 4-layer board with 57°C/W VI. 100% production tested at 25°C; guaranteed by design solid ground plane) and characterization testing for industrial temperature range. Stresses above those listed under Absolute Maximum Ratings 100% production tested at temperature extremes for may cause permanent damage to the device. This is a stress military devices. rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
