Absolute Maximum Ratings

CAUTION: The absolute maximum ratings are stress ratings only. Stresses greater than those listed below can

cause permanent damage to the device. Functional operation of the HS401x at absolute maximum ratings is not

implied. Exposure to absolute maximum rating conditions might affect device reliability.

Recommended Operating Conditions

Important note: The HS401x series sensors are optimized to perform best in the more common temperature and

humidity ranges of 10°C to 50°C and 20% RH to 80% RH, respectively. If operated outside of these conditions

for extended periods, especially at high humidity levels, the sensors may exhibit an offset. In most cases, this

offset is temporary and will gradually disappear once the sensor is returned to normal temperature and humidity

conditions. The amount of the shift and the duration of the offset vary depending on the duration of exposure and

the severity of the relative humidity and temperature conditions.[1] The time needed for the offset to disappear

can also be decreased by using the procedures described in sections 8 and 9.
