CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact
product reliability and result in failures not covered by warranty.
NOTES:
4. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief
TB379 for details.
5. For θ_JC, the “case temp” location is on top of the package and measured in the center of the package between pins 6 and 15.
6. The ISL12022M Oscillator Initial Accuracy can change after solder reflow attachment. The amount of change will depend on
the reflow temperature and length of exposure. A general rule is to use only one reflow cycle and keep the temperature and
time as short as possible. Changes on the order of ±1ppm to ±3ppm can be expected with typical reflow profiles.
DC Operating Characteristics RTC Test Conditions: V_DD = +2.7 to +5.5V, T_A = -40°C to +85°C, unless otherwise
stated. Boldface limits apply over the operating temperature range,
-40°C to +85°C.
