ADS131M02: How to use SPI interface 1.8V?

Hi Rice,Lee,

in order to operate ADS131M02 on a 1.8V SPI bus, you simply need to provide a 1.8V DVDD supply to the device and short the DVDD and CAP pins together as described in the datasheet. You can still keep the AVDD supply at 3.3V in that case.

Joachim Wuerker

This is what is in the data sheet, but what is written incorrectly?

Hi Rice,Lee,

Please read the datasheet in detail, of course we cannot fit all of the information on the first page

See below from the recommended operating conditions about the conditions to operate the ADS131M02 at 1.8V IO voltage. This is as Joachim described.
