As of February 2, 2026, the NXP MEMS Sensor products have been transferred to STMicroelectronics. For details on the transferred products, see this page. Please reach out to STMicroelectronics for further information.
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
