AD9218-EP Enhanced Product ABSOLUTE MAXIMUM RATINGS Table 5. THERMAL RESISTANCE Parameter Rating
Thermal performance is directly linked to printed circuit board VD, VDD 4 V (PCB) design and operating environment. Careful attention to Analog Inputs –0.5 V to VD + 0.5 V PCB thermal design is required. Digital Inputs –0.5 V to VDD + 0.5 V θ REF JA is the natural convection, junction to ambient thermal IN Inputs –0.5 V to VD + 0.5 V resistance measured in a one cubic foot sealed enclosure. Digital Output Current 20 mA Operating Temperature Range –55°C to +105°C θJC is the junction to case thermal resistance. Storage Temperature Range –65°C to +150°C
