SBOS823 December 2018 OPA2313-Q1
CMRR for the OPA2313-Q1 device is specified in several ways so the best match for a given application may be used; see the Electrical Characteristics. First, the CMRR of the device in the common-mode range below the transition region (VCM < (V+) – 1.3 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 over the entire common-mode range is specified at (VCM = –0.2 V to 5.7 V). This last value includes the variations seen through the transition region, as shown in Figure 7.
