Does the output current of the MPX5999D affect the long-term stability of the sensor?
Now the maximum output current（Io+） in our product is 0.2 mA。
Dear Li Sun,
we don't have records regarding the higher, than typical output current affecting the long term stability.
I could only suggest you to decrease load on the Vout pin, which should decrease the output current.
With Best Regards,
Jozef
