common-mode rejection ratio

[′käm·ən ‚mōd ri′jek·shən ′rā·shō]
(electronics)
The ratio of the gain of an amplifier for difference signals between the input terminals, to the gain for the average or common-mode signal component. Abbreviated CMRR.

Over this supply range, the amplifier maintains a common mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) of more than 120 db and a typical low input bias current of 10 nA.
Very high common mode rejection min 10kV/ms at VCM = 1500V (VCM = 1000V for ACPL-M61U)
Additionally, the IRS2117 and IRS2118 feature common mode rejection of 50V/ns.
Better common mode rejection performance prevents erroneous driving of IGBTs and ensures reliable operation under noisy environments.
The EMI2121 single pair CMF, EMI4182 dual pair CMF and EMI4183 triple pair CMF all offer a common mode rejection of 15 decibels (dB) (typical) at 500 megahertz (MHz) and an insertion loss of only 1.
The device also features a fast switching speed, up to 15Mbit/sec, and uses Fairchild's proprietary Optoplanar[R] packaging technology and optimized IC design to achieve high common mode rejection (CMR) of 20kV/os minimum, allowing the device to operate in noisy industrial environments.
With high common mode rejection ratio characteristics (77dB to 86 dB minimum, depending on performance grade), the low-cost AD629 does this effectively, making it well suited for applications such as high-side current sensing, isolation, input protection, battery voltage monitoring, motor control and power-supply current monitoring.
The analog front-end (AFE) in the XRD9815 is fully differential and provides common mode rejection of lamp noise and system noise that accumulates on cable connections.
Superior common mode rejection of up to 30kV/s is achievable, while continuing to communicate through the event.
