Common Mode Rejection Ratio (CMRR)
1/2 LTC6943
The LTC6943, when used as a differential to single-ended
converter rejects common mode signals and preserves
differential voltages (Figure 1). Unlike other techniques,

the LTC6943’s CMRR does not degrade with increasing
common mode voltage frequency. During the sampling

mode, the impedance of Pins 1, 2 (and 9, 10) should be
balanced, otherwise, common mode signals will appear
C – 10
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 shorting Pins 6 and 11 and by observing, with a
