Datasheet ADIS16490 (Rev. A) ABSOLUTE MAXIMUM RATINGS THERMAL RESISTANCE Table 4. Parameter Rating
Thermal performance is directly linked to printed circuit board Acceleration (PCB) design and operating environment. Careful attention to Any Axis, Unpowered 1500 g PCB thermal design is required. Any Axis, Powered 1500 g θJA is the natural convection junction to ambient thermal VDD to GND −0.3 V to +3.6 V resistance measured in a one cubic foot sealed enclosure. Digital Input Voltage to GND −0.3 V to VDD + 0.2 V θJC is the junction to case thermal resistance. Digital Output Voltage to GND −0.3 V to VDD + 0.2 V Operating Temperature Range −40°C to +105°C The ADIS16490 is a multichip module, which includes many Storage Temperature Range active components. The values in Table 5 identify the thermal 1 −55°C to +150°C response of the hottest component inside of the ADIS16490, Barometric Pressure 2 bar with respect to the overal power dissipation of the module. 1 Extended exposure to temperatures that are lower than −40°C or higher This approach enables a simple method for predicting the than +105°C can adversely affect the accuracy of the factory calibration. temperature of the hottest junction, based on either ambient or case temperature. Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a For example, when the ambient temperature is 70°C, the hottest stress rating only; functional operation of the product at these junction inside of the ADIS16490 is 76.7°C. or any other conditions above those indicated in the operational TJ = θJA × VDD × IDD + 70°C section of this specification is not implied. Operation beyond TJ = 22.8°C/W × 3.3 V × 0.089 A + 70°C the maximum operating conditions for extended periods may affect product reliability. TJ = 76.7°C
