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:
5. Measured with no filtering, distance of 10” from source, intensity set to 55kV and 70mA current, 30s duration. Other exposure levels should be
analyzed for Output Voltage drift effects. See “Applications Information” on page 7.
6. 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.
7. For θ_JC, the “case temp” location is taken at the package top center.
8. Post-reflow drift for the ISL21070 devices will range from 100μV to 1.0mV based on experimental results with devices on FR4 double sided boards.
The design engineer must take this into account when considering the reference voltage after assembly.
