ADXL212 ABSOLUTE MAXIMUM RATINGS THERMAL RESISTANCE Table 2.
θ
Parameter Rating
JA is specified for the worst-case conditions, that is, a device soldered in a circuit board for surface-mount packages. Acceleration (Any Axis, Unpowered) 1000 g Acceleration (Any Axis, Powered) 1000 g
Table 3. Thermal Resistance
VS −0.3 V to +7.0 V
Package Type θJA θJC Device Weight
Output Short-Circuit Duration Indefinite 8-Lead Ceramic LCC 120°C/W 20°C/W <1.0 g (Any Pin to Common) Operating Temperature Range −55°C to +125°C
ESD CAUTION
Storage Temperature Range −65°C to +150°C Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress 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 device reliability.
