Dear All:
I use LMP90080 as AFE.
Can I give VA=DC 5V, and VIO= DC 3.3 V ? interface with MSP430G by SPI and MSP430G is power with DC 3.3V.
Sensor side is power by DC 5V.
Thanks !

Hi Marshall,
Yes Va and VIO can be different voltages. See the "VA and VIO" section on page 40 of the datasheet and Figure 67 on page 47 for an example.
