How to give power supply to the IMU sensor ASM330LHB

[Deviprasad Bokkisam]

The IMU sensor is  working on two input voltage supply 1.Vdd - Core supply 2.Vddio - digital I/O supply.My questions are in below.

1.Is it better to supply the Vdd and Vddio seperately from two voltage regulators? 

2.Is it better to supply the Vdd and Vddio from single voltage regulator?

3.Which method 1 or 2 is best, to increase the accuracy of IMU sensor?

4.What are power supply specifications(Ex: Output voltage accuracy and PSRR-power supply rejection ratio etc)?

Hi @Deviprasad Bokkisam ,

About 1-2 question there is no difference to supply the vdd and vddio with one or two different voltage regulator if they are at the same voltage.

About question 3: method 1 or two doesn't change the accuracy of IMU sensor.

For the power supply specifications you can refer to the datasheet.

However, we do not provide PSRR values as it is only tested in characterization and is not guaranteed in production.
