ADS131M08: ADS131M08 EXT.Vref?

Part Number: ADS131M08
Other Parts Discussed in Thread: ADS131E08

The ADS131M08 EXT.REFIN MAX is described in the datasheet as AVDD + 0.3V and the Recommended Operating Condition is 1.1V ~ 1.3V.
If REFIN is applied with 2V, can Reference voltage operate with 2V? Or does it work at 1.3V?
Thank you.

Hello Kwon,

Unfortunately, the recommended operating conditions are correct here. 1.1V - 1.3V is what is allowed for the external reference voltage. See other posts here:

If you are set on using an external reference, like recommended in the other post, ADS131E08 might be a good fit for you.

Best,

-Cole
