Will the MP3V5010DP pressure sensor work at all below 2.7V?

[BillHoyt]

The MP3V5010DP pressure sensor is rated to operate from 2.7V to 3.3V, but if we ignore its accuracy, will the sensor still operate (inaccurately) below 2.7V?  I have a prototype that we're designing that could operate down to 2.0V if the pressure sensor could at least function down to there.  The measurements could be very far off in this specific application...

Hi,

It is not recommended to use the MP3V5010DP with a power supply below 2.7V since data is not characterized at this voltage, but according to the ratiometric nature excitation range of this sensor, it should work, but the accuracy and linearity data of the datasheet would change (operating the device at a different range may induce additional error).

The output given by the sensor is not specified because there is no characterization data at this voltage.

Have a great day,
Jose Reyes
