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:
1. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
2. 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: VDD = +2.7 to +5.5V, TA = -40°C to +85°C, unless otherwise stated.
