PCB thermal design is required. Mechanical Shock Survivability Any Axis, Unpowered 2000 g The ADIS16467 is a multichip module that includes many Any Axis, Powered 2000 g active components. The values in Table 4 identify the thermal VDD to GND −0.3 V to +3.6 V response of the hottest component inside of the ADIS16467, Digital Input Voltage to GND −0.3 V to VDD + 0.2 V with respect to the overall power dissipation of the module. Digital Output Voltage to GND −0.3 V to VDD + 0.2 V This approach enables a simple method for predicting the Calibration Temperature Range −40°C to +85°C temperature of the hottest junction, based on either ambient or Operating Temperature Range −40°C to +105°C case temperature. Storage Temperature Range1 −65°C to +150°C For example, when the ambient temperature is 70°C, the hottest Barometric Pressure 2 bar junction temperature (TJ) inside of the ADIS16467 is 76.7°C. 1 Extended exposure to temperatures that are lower than −20°C or higher TJ = θJA × VDD × IDD + 70°C than +85°C can adversely affect the accuracy of the factory calibration. T Stresses at or above those listed under Absolute Maximum J = 158.2°C/W × 3.3 V × 0.044 A + 70°C Ratings may cause permanent damage to the product. This is a TJ = 93°C stress rating only; functional operation of the product at these
