8.4.5 Common-Mode Rejection

The CMRR for the TLV854x is specified in two ways so the best match for a given application may be used. First, the CMRR of the device in the common-mode range below the transition region (VCM < (V+) – 1.2 V) is given. This specification is the best indicator of the capability of the device when the application requires use of one of the differential input pairs. Second, the CMRR at VS = 3.3 V over the entire common-mode range is specified.
