Hi,

is there a limit other than the FS input range to the allowed common mode voltage range of the ADS8317 and what is its CMRR?

thanks,

Katharina

Hi Katharina,

There are a few graphs on page 17 of the datasheet that depict the common mode voltage limit which is V_DD - 1.2V. You've got a slightly wider negative range when running in differential mode. We'll check to see if there is and data available for CMRR over frequency.

Hi Katharina,

I am sorry for the delay, but there is no characterization data available for CMRR for the ADS8317.
