MPXM2010GS Supply Voltage

[markackerson1]

MPXM2010GS parametric page 0 - 10kPa Compensated Pressure Sensor | NXP specifies supply voltage min is 1V:

Supply voltage [min] (V)	1.0
Supply voltage [max] (V)	16.0
Supply voltage [typ] (V)	10

https://www.nxp.com/docs/en/data-sheet/MPX2010.pdf data sheet specifies supply voltage 10V typ  and 16 V max.  Note 2 in the data sheet states "Device is ratiometric within this specified excitation range. Operating the device at a different range may induce additional error due to device self-heating. VS — 10 16 VDC"

Questions:

Can the MPXM2010GS operate with 5V supply?

What are the tradeoffs operating at 5V vs 10V or 15V supply (ie SNR)?

Thanks,
Mark

Hi,

Answering to your questions:

Can the MPXM2010GS operate with 5V supply?

[A] Yes, you can use the MPXM2010GS with a voltage supply of 5V, although the recommended value is 10V since spec may change. Take in mind that the output is radiometric with the input voltage, so, output voltage range will be smaller than using 10V.

What are the tradeoffs operating at 5V vs 10V or 15V supply (ie SNR)?

[A] Offset, noise, linearity, can vary, but nothing that can affect the measurements.

You can use the application note AN4010 as a guideline about to use this sensor with different supply voltages, in page 4 is described an example using 5V as the supply voltage.
