regardless of its differential gain. When set to unity
gain, the circuit of Figure 8 has 0 dB CMRR. The
U-pad attenuator formed by R9~R11 attenuates dif-
ferential signals but not common-mode signals, so
the CMRR of this circuit is actually -9 dB at mini-
mum gain: when the 5173 is set for 0 dB gain, differ-
ential input signals are attenuated by 9 dB, but

vide high common-mode rejection, so the system
CMR including converter may well be acceptable, but
consider what happens if a large common-mode sig-
