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 8.
5. 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.
6. 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.
Electrical Specifications (ISL21070-xx, V_OUT = 1.024V to 2.048V) V_IN = 3.0V, T_A = -40°C to +85°C,
I_OUT = 0, unless otherwise specified. Boldface limits apply over the operating
temperature range, -40°C to +85°C.
