MP3V5010DP

[yulongsun]

在我的设计中使用了MP3V5010DP，在没有压差时，输出脚电压为0.283V，另外一个芯片输出为0.261V，而手册中显示MP3V5010DP的输出范围是0.1V-3.1V？？

Used MP3V5010DP in the design of I, in the absence of pressure difference, the output voltage of 0.283 V feet, another chip output is 0.261 V, and the output of the manual shows MP3V5010DP range is 0.1 V to 3.1 V  ??

Hi Yulong,

As you can see in the MP3V5010DP data sheet, the Voff ranges from 0.1V to 0.38V, so the voltage you are measuring is within the spec limits.

Let me know if you have any other questions or if I misinterpreted your question.

Regards,

Tomas

Hi,Tomas Vaverka

       In another system MP3V5010DP and MP3V5004DP I use 2.5 V power supply, the output amplitude decreases, other parameters had not found the problem.But in the manual power supply range is 2.7 V to 2.7 V, don't know whether it can use 2.5 V power supply, and influence for other parameters?

Hi Yulong,

I do not have characteristics for lower voltages than the specified one in the datasheet, but both parts work reliably at 2.5V. And as you already noticed, both the output offset voltage and sensitivity scale linearly with applied supply voltage.

Regards,

Tomas

Thanks Tomas Vaverka ! The problem has been resolved.
