JAJSI11B October 2019 – February 2021 ADS131M08
PRODUCTION DATA
The ADS131M08 core digital voltage of 1.8 V is created from an internal LDO from DVDD. The CAP pin outputs the LDO voltage created from the DVDD supply and requires an external bypass capacitor. When operating from DVDD > 2.7 V, place a 220-nF capacitor on the CAP pin to DGND. If DVDD ≤ 2 V, tie the CAP pin directly to the DVDD pin and decouple the star-connected pins using a 100-nF capacitor to DGND.
