Common Mode Rejection Ratio (CMRR)
1/2 LTC1043
The LTC1043, when used as a differential to single-ended
converter rejects common mode signals and preserves
differential voltages (Figure 1). Unlike other techniques,

the LTC1043’s CMRR does not degrade with increasing
common mode voltage frequency. During the sampling

mode, the impedance of Pins 2, 3 (and 11, 12) should be
reasonably balanced, otherwise, common mode signals
C – 12
will appear differentially. The value of the CMRR depends
on the value of the sampling and holding capacitors
(C S , C H ) and on the sampling frequency. Since the

common mode voltages are not sampled, the
common mode signal frequency can well exceed the
sampling frequency without experiencing aliasing
phenomena. The CMRR of Figure 1 is measured by
