HUMIDITY SENSITIVITY

The ADR3625\ADR3630\ADR3650 are packaged in an MSOP.

However, moisture absorption from the air into the package

changes the internal mechanical stresses on the die, causing shifts

in the output voltage. Figure 67 shows the effects of a step change

in relative humidity on the output voltage over time. The humidity

chamber is maintained at an ambient temperature of 25°C, while

the relative humidity undergoes a step change from 30% to 70%.

The relative humidity is maintained at 70% for the duration of the

testing. Note that the output voltage shifts quickly compared to the

overall settling time, following the step change in relative humidity.

70% Relative Humidity (RH))
