Figure 4 illustrates the CS5525/26 connected to
measure ground referenced unipolar signals of a
positive polarity using the 1 V, 2.5 V, and 5 V input
voltage ranges on the converter. For the 25 mV, 55
mV, and 100 mV ranges the signal must have a
common mode near +2.5 V (NBV = 0V).

The CS5525/26 are optimized for the measurement
of thermocouple outputs, but they are also well
suited for the measurement of ratiometric bridge
