CS5525 CS5526

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

transducer outputs. Figure 5 illustrates the

CS5525/26 connected to measure the output of a

ratiometric differential bridge transducer while op-

erating from a single +5 V supply.
