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. 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 11.

5.

θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

6. For

θJC, the “case temp” location is the center of the exposed metal pad on the package underside.

7. For

θJC, the “case temp” location is taken at the package top center.

8. Post-reflow drift for the ISL21440 device voltage reference output will range from 100mV 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.

Analog Specifications V+= +5.0V. V- = GND = 0V unless otherwise specified, TA = +25°C. Boldface limits apply over the operating

temperature range, -40°C to +125°C.
