THERMAL RESISTANCE Table 2.
Thermal performance is directly linked to printed circuit board (PCB) design and operating environment. Careful attention to
Parameter Rating
PCB thermal design is required. AVDD to AVSS −0.3 V to +3.96 V IOVDD to DGND −0.3 V to +3.96 V θJA is the natural convection, junction to ambient thermal IOVDD to AVSS −0.3 V to +5.94 V resistance measured in a one cubic foot sealed enclosure. AVSS to DGND −1.98 V to +0.3 V θJC is the junction to case thermal resistance. Analog Input Voltage to AVSS −0.3 V to AVDD + 0.3 V Reference Input Voltage to AVSS −0.3 V to AVDD + 0.3 V
